The reality is that demand-side economics has stronger and more intelligent underpinnings (give money to individuals --> they spend --> increase demand --> hiring). Giving more cash to companies doesn't induce hiring; demand for products induces hiring.
It doesn't matter if borrowing and spending (some might call it "investing") money is good fiscal policy— "spending" is just wrong.
Please. The government spent far less during Clinton's administration (the last vaguely fiscally responsible president), and I don't recall having to step over that many starving homeless people to get to work.
Whether you believe FDR's New Deal helped or hindered recovery from the Great Depression, the simple, business-oriented financials of it would seem to indicate that right now is the time to be building roads, trains, dams, nuclear plants, etc.
Instead, we cut funding to things which may pay off later in order to funnel money into which have an inevitable negative rate of return, like imprisoning people, security theater, and killing people on the other side of the globe.
We're not paying it back. Any of it. At best we can cover the interest payments.
Why do you think this won't blow up in our faces?
