it might be that i didn't get the point of your comments (assuming you are also the grandparent AC) in relation to the commentary about idle reserves created by corporate tax cuts.
to recap the conversation i think we're having so far: Aighearach says "corporate tax cuts are not keynesian as they create wealth for large businesses that isn't being used."
AC says "that money isn't just sitting around doing nothing."
i say "these companies do have all this cash, and are doing nothing with it but hoarding, certainly not stimulating economy. citations provided, mothafucka."
AC says "(assumed: the money is actually in the banks) the banks don't actually have this money on hand, most is tied up in financial instruments and loans." i can't tell if your point is a semantic one (the money is not in GE's big cash room, it is being used by banks!) or an economic one (the money in use by the banks is therefore stimulating the economy).
am i on the same page as you, now? if your point was the latter...
if so, i would reply that this money is doing very little positive for the economy as a whole; financial instruments favored by banks produce nothing of actual value, though they do create bubbles which have the short-term appearance of value, until the eventual pop. loans are being given to non-major industry players even more rarely than before, and the large profitable businesses (as noted by their 1s and 0s) have little need for the leverage. this leaves national bonds, which is not unlike stuffing the cash in the mattress.
none of these would produce anywhere near the good, services, and wages that there would have been if the large companies had spent the money, by a long shot.
if your point was just the semantic "the money isn't just sitting in Microsoft's money warehouse," goddamnit for making me type all that.
