Government grew during the Bush administration. Government spending almost doubled.
Have you forgotten about 2 wars of adventure & the consumption of an enormous amount of right wing comfort food pork, military & so called "security" spending?
That's not the point, anyway. The point is that freeing the financial sector of the bonds of meaningful regulation created financial catastrophe, that freer markets aren't necessarily better markets, at all.
We learned that circa 1931, but became convinced that the lessons of history no longer applied. Obviously, we were mistaken.
Govt failed to do its job, to put a fence around the wolves of Wall St, to inhibit the self destructive tendencies of financialized capitalism. And now, of course, the Right Wing doesn't want to let this crisis go to waste, so what they suggest, demand, is that govt fail to do their job again, allow the economy to enter into a debt deflation spiral.
If we want less welfare, then we need more jobs, and the private sector is disinclined to create them atm. That's just the obvious truth. Therefore, it's up to govt to do so, regardless of the maudlin hand wringing & pearl clutching on the part of Repubs shilling for the wealthy. If we don't want to borrow to accomplish that, we need to raise taxes to do so, starting with those most able to pay.
