Déjà vu?
Keynes' General Theory works only when it is combined with its theories about fiscal policy--taxation--and government spending. Reasonably easy access to capital with low interest rates is fundamental but insufficient.
Apologists for the corporatocracy attempt to justify "conservative" (actually, corporatist) policies, which ensure transfer of resources and wealth from the people to the privileged few by market forces, but only those that benefit the greedy and wealthiest in the market (a control exercised by the largest corporations: banks, oil companies, and other transnationals because of extremely low taxes, subsidies, and lack of competition and effective regulation).
"Conservative", "market-based" theories fail consistently, but Keynesian theories explain them effectively:
"The argument conservatives make against government spending—“it has to come from somewhere”—is actually no less true for private investment. If dollar-for-dollar crowding out were true, therefore, it would be just as impossible for private investment to pull the economy out of a recession. This, of course, would be nonsense unless the economy was already at full employment (and an increase in one kind of production would have to come at the expense of some other kind of production)."
"If the economy were already operating at full capacity—imagine a situation in which all workers are employed, factories are humming with activity 24/7, and no unused resources would be available to expand production if demand increased—the argument that increased government spending could not increase overall economic output might be plausible. But that is manifestly not the current economic situation."
(See
http://www.dollarsandsense.org/archives/… Spending that creates employment is a form of investment. Such investment may be private (in which case it is expected to produce profits) or public (in which case it can be spent on modern, high-speed rail, an infrastructure that facilitates operations of businesses doing work in the US, education and health care--which boost labor productivity, etc.).
If private investment is not forthcoming for lack of demand, then government spending on needed projects or services is not only necessary but a also bargain to the taxpayer (low interest rates and lower labor costs). Furthermore, by putting people to work, it provides them income to spend. The poor and middle classes spend almost all their income on goods and services (food, housing, transportation, clothing, etc.). As more people spend, demand goes up. The private sector, recognizing that rising purchasing power will reward private investment in the form of profits, scrambles to invest--hiring even more people.
In short, much more is involved in Keynesian theories than monetary policy (money supply) and fiscal policy (taxation).
To avoid exposure of their fallacious theories, Corporate America has taken ownership or control of our media, which cannot effectively inform the public of the abuses and schemes of their owners or major advertisers. It also spends heavily on lobbyists, "think tanks" whose conclusions are provided ahead of research, and propaganda intended to cause the American people to fight among each other, blaming those forced onto welfare, those who are of different races and cultures (especially undocumented immigrants), and anyone who challenges their biases and prejudices--lumping the latter into the undefined classifications of "liberal," "socialist," "Marxist," Godless," etc.
Calling people concerned about the needy "Godless" is irony taken to the nth degree. The very people labeling those who do not toe their ideological dogmata are in thrall to the anti-Judeo-Christian values of Ayn Rand--the embodiment of Godlessness!
