"Until people are working the economy isn't."
The problem with Democratic economics is that they don't take it to the next step of "until people are hiring."
The core of economic growth is people making a healthy profit on what they do, generating real surplus wealth for business growth and, incidentally, paying taxes.
Assuming you can get everyone working by dumping tax money into the economy also misses that crucial step in the process.
Put it this way: If every corporation was non-profit, what would the tax revenue stream look like?
