I never offered that Greenspan's dropping of interest rates to near zero in the early years of the Bush Admin was good policy, and neither did Keynsians. Greenspan never was a Keynsian, but rather a monetarist.
Keynsians today offer that low rates will not have the desired effect because of the liquidity trap phenomenon, and some have argued that ever since the crash of 2008. What's needed is direct efforts to create jobs, therefore demand, and the private sector simply is not doing that, nor do they have any reason to do so because of low demand. catch-22. If govt borrowing is out of the question to do so, then taxes at the top need to be raised for the purpose- it's not like that money is going anywhere otherwise.
The bottom line is that money is what's not real, but a system for assigning ownership of what's real, while actual goods and services are what's real.
Putting people to work with imaginary/manufactured money creates real goods and services, that can then be distributed.
If done to excess, it's inflationary; history shows, which so many seem ignorant of, that the benefits generally are much bigger than any harm of inflation in a recovery.
This is why people who actually have a clue like Paul Krugman make the politically unpopular statement 'the stimulus is much too small' - big debt or not.
He understands, which the right doesn't, that austerity will make it HARDER to pay it.
If there were a business losing money, one approach might be 'pay for improvements, hire more salespeople, increase the marketing budget'.
That might increase sales and raise money to pay off the debts.
A second approach would be austerity. "Reduce the hours we're open, we can't afford so many. Cut the cleaning expenses, we can't afford them. Reduce the marketing budget, we can't afford ads. Cut salaries, we can't afford them. Sell off parts of the business to raise money."
Then, when the business loss the income of what it sold, the customers who avoid the store because it isn't clean, who don't come because of less marketing, the loss of productivity as good employees leave after salary reductions, they look at the debt and say 'now it's even harder to pay'.
That's a bit like the country, except the business can go out of business, the country can't. What the country can do is become a much poorer country from bad policies.
And when the rich kill the goose that laid the golden egg by demanding their incomes go up more than then economy - much less the hundreds of percent they've been going up - by taking ALL economic growth after inflation for decades - they're making our country poorer and hurting it eventually. Growth has continued to be decent - all of which they've taken - but that's not going to last. It would if the growth were distributed more in the country. It's not.
