Ok, the economy is tanking again.  

Can we do something about it?  

 Should we?  

Conservatives will tell you that we can't, and even if we could, we can't afford it.  But I say let's call their bluff by responding first to the problem of affordability.  Let's raise taxes on capital gains and dividends, and end corporate tax givaways.  If we add a tax increase at the top, we'll be on our way to solvency.

 ... Then, let's add a 2 year stimulus that includes only direct stimulus - money for public sector jobs and for public works, say a half a trillion each year for two years.  That should help.

By the way, the stimulus did work, not as much as hoped for, but it was counteracted by drastic state and local reductions.  Paul Krugman more or less predicted that it would play out that way.

 Anything more? Not really.  Yes, I could say a lot more, but if you agree with me, you don't need to hear me.  If you don't, you won't listen.
