Put it this way: Suppose that you actually liked a caste society, and you were seeking ways to use your control of the government to further entrench the advantages of the haves against the have-nots. What would you do?
One thing you would definitely do is get rid of the estate tax, so that large fortunes can be passed on to the next generation. More broadly, you would seek to reduce tax rates both on corporate profits and on unearned income such as dividends and capital gains, so that those with large accumulated or inherited wealth could more easily accumulate even more. You'd also try to create tax shelters mainly useful for the rich. And more broadly still, you'd try to reduce tax rates on people with high incomes, shifting the burden to the payroll tax and other revenue sources that bear most heavily on people with lower incomes.
Meanwhile, on the spending side, you'd cut back on healthcare for the poor, on the quality of public education and on state aid for higher education. This would make it more difficult for people with low incomes to climb out of their difficulties and acquire the education essential to upward mobility in the modern economy.
And just to close off as many routes to upward mobility as possible, you'd do everything possible to break the power of unions, and you'd privatize government functions so that well-paid civil servants could be replaced with poorly paid private employees.
It all sounds sort of familiar, doesn't it?
Where is this taking us? Thomas Piketty, whose work with Saez has transformed our understanding of income distribution, warns that current policies will eventually create 'a class of rentiers in the U.S., whereby a small group of wealthy but untalented children controls vast segments of the US economy and penniless, talented children simply can't compete.' If he's right--and I fear that he is--we will end up suffering not only from injustice, but from a vast waste of human potential.
Goodbye, Horatio Alger. And goodbye, American Dream.
Untalented children inheriting America from their dear old dad? There's no way that could ever happen? Is there? Um...
