Progressive Taxes Worsen Inequality?

 Felix Salmon has a counter-intuitive thought:

[W]hen you have a progressive tax system, especially when there are surcharges on people making seven-figure incomes, you also have a system where for any given level of national income, the greater the inequality, the greater the government’s tax revenues. And indeed federal revenues have been rising faster than median wages for decades now, thanks to the rich getting ever richer.

Given the government’s insatiable appetite for cash, it’s only natural that it would prefer to tax plutocrats, spending some of that money on poorer Americans, rather than move to a world where poorer Americans earn more (but still don’t pay that much in taxes), and the plutocrats earn less, depriving the national fisc of untold billions in revenue.

The government’s interests, then, are naturally aligned with those of the plutocrats and when that happens, the chances of change naturally drop to zero.
