So clearly that a liberal should understand.

There are three ways government can get the money for a stimulus package. It can tax, borrow or inflate the currency by printing money. If government taxes to hand out money, one person is stimulated at the expense of another who pays the tax, who is unstimulated and has less money to spend. If government borrows the money, it’s the same story. This time the unstimulated person is the lender who has less money to spend. If government prints money, creditors, and then everyone else, are unstimulated. As my colleague Russell Roberts said in a NPR broadcast, “It’s like taking a bucket of water from the deep end of a pool and dumping it into the shallow end. Funny thing—the water in the shallow end doesn’t get any deeper.”

Politicians are too stupid to manage the economy.  I doubt they can manage their own finances. 

Walter Williams says the best stimulus would be making the 2003 tax cuts permanent.  It would he said:

According to economists Tracy Foertsch and Ralph Rector, making the 2003 tax cuts permanent will annually add $76 billion to the GDP, create 709,000 jobs and add $200 billion to personal income.

But then they won’t do that because it’s doesn’t fit Congress’s temperament of taxing anything that moves and subsidizing anything that doesn’t.
