Actually it's not a new idea that too steep an income inequality harms economic growth as much as too little.
I like the part about the difference between talking about poverty and income inequality.
Yah, it's been around for a bit. This crazy notion that for consumption to continue people have to have money proportionate to to the value of goods being offered for sale.
A couple of different options come to mind if you are planning an economy so that you and your friends can have it all... You can force wages down in an acceptable way in the worlds largest economy, the North American/European one, by offering lower cost goods made in third world countries. This has the advantage of keeping the body politic on side, which is always a nice warm feeling.
Another option, and these can happen in the same time frame, is to ensure ignorance of the costs of getting wealthy, cancer, acid rain, sun burns, global warming, soil depletion, third world conditions and not just in the third world... Of course this is trickier because, unlike the focus presentation of having the horn of plenty overflowing, people can actually see forests being stripped, water being polluted, and housing becoming exorbitant.
It's not just about consumption. People are more productive if they feel they're getting a fair share of the pie. They cooperate more. And justice system and medical costs go down the less poverty you have. You need a certain amount of inequality to spur people on, after that you're just shooting yourself in the foot.
Those environmental problems you mention would come about even if we had less income inequality. If we were all poor, no way could the planet support 7 billion people. If the whole world is middle class (as of course it wants to be) no way the planet has enough resources to support that lifestyle for 7 billion for very long.
True, it's not just about consumption, although consumption has been the major economic force behind wealth accumulation and disparity. I wonder if we have changed the ratio at all in this last 50-60 years, or if we have just managed to maintain the same kind of social structure but over a larger proportion of the planets population. So our health has improved by being middle income earners but is the middle of millions on one side and pennies on the other side also the middle of the population? I don't think so.
I think that consumption affects environmental conditions in a couple of ways. Our usage of resources is as you say not sustainable, but also our mental attitude towards consumption as a good allows us to set aside or more likely not notice the effect of our consumption. Whether we are all poor, or all middle class over the coming years is up to us and I suggest that the middle might be less than current North american consumption standards. Which could still allow for a pretty decent standard of living.
The whole topic of 'income inequality' is based on envy. If you're jealous of the wealthy then study what they do and then become wealthy yourself.
No one's stopping you.
But if all you want to do in life is to utilize the power of government to steal on your behalf then you deserve to be stopped.
The second point explained by this, 'Higher taxes on the rich may be a logical response to rising income inequality, but actually levying those taxes is getting harder in an age of global capital flows.' is really important. A corporate citizen doesn't have the same motivations as a small community based business. In fact I question the whole value of having such a citizenship in a global marketplace.
In this discussion where the wealth concentrations evade responsibility, as Mr Buffet suggests, why would we accept them as countrymen. The same thing with different motivations as Conrad Black going for lordship. No allegiance is binding but that of corporate continuance.
That may change for them when all human and natural capital has been exploited to the point where our current recession is worldwide and all the money devalues, but I'm not sure corporate intelligence will grasp it even then. Where have all the flowers gone?
Back in the 19th century, we had children being worked for 14 hours a day, people being paid in worthless scrip that could only be redeemed at a company store, people often ending up impoverished or dead if they suffered from medical problems they had no control over, and most people not having a chance for a better life because they had little or no opportunity for an education.
I have a hard time seeing how exactly most people were really free back then. Hell, Communism actually emerged in response to those appalling conditions.
However, with things like minimum wages, public health care, limited work days and free education, millions upon millions of people actually gained more leisure time, more discretionary income, and more of a capacity to improve their situations. In short, they became more free thanks to a positive government intervention.
What's a guy supposed to do if he loses his job because a business owner f*cks up or the market crashes? How's he supposed to feed his family until he finds another job? What if his kid has a crippling medical condition that requires expensive medicine or surgery, and he can't pay for it because he has no health insurance? How's he supposed to consume and contribute to the economy? How much of a capacity does he actually have to exercise his innate rights and freedoms?
Of course government intervention can do just as much harm as it can good. Of course unions can overreach and go too far. Of course taxes can be too high. Of course cuts sometimes need to be made. The people who point out these things are quite right, and I agree with them. I also agree about the horrors of Communism-to paraphrase Kent Brockman, Marxism simply doesn't work.
But what I don't get is why it has to be an all-or-nothing thing. Apparently a society can only either be a heavily taxed welfare state or a radically laissez-faire society. Why can't we recognize both the positive advantages of private enterprise and capitalism AND government social programs? They each have their strengths and weaknesses, and in the best circumstances they can complement each other's strengths and compensate for each other's weaknesses.
Back in the 1930s, many Canadian business owners actually came to support the idea of a social safety net both because it undermined the appeal of Communism and also gave many more members of the public more money to spend on the products those business owners were making. If Canada has prospered, it's been through a worthwhile combination of individual, private enterprise and collective government action.
It would be great, how do you establish such even handedness? My only suggestion would be for people to walk out on the big corps that seem focused on their central control.
I sympathize with Mr. Milanovic's ideas, but just calling for sharing the wealth without having a real plan is a non-starter. The main current plan is to raise incomes on the wealthy, which just sends money to the government. What happens next? Not much, at least not currently. Right now the words "sharing the wealth" conjure memories of George W. Bush giving everyone $300; a lot of long-term good that did.
Bill O'Reiley (hold your rage) made a very good point during one of his appearances on The Daily Show with Jon Stewart. I wish I could find a video that wouldn't block Canadian IP addresses, but he said he's be more than willing to pay more taxes if he thought it would do any good. I don't completely agree with him on the federal level, but my taxes in California will go up next month and I know the money will be wasted on giving ex-police chiefs a quarter-million dollar annual pension while city buildings can't pay the electric bill.
