Quote from PragmaticIdeals:
Asset price inflation will inevitably trickle into consumer markets.
And if only a small portion of it does (because it's being countered by deflationary forces), this is arguably WORSE because it means "main street" has lost jobs and purchasing power whereas capital-owners have boosted their REAL wealth (due to the printing press and not "hard work" -- technically due to failing in the free market).
Often times, we economists attempt to rationalize silly policies like printing money with a range of theories.
These theories have merit at the proximate level. Proximate being the key word. On a macro / systemic level, these types of policies will likely only aggravate matters and inequity.
You can't just print money (or increase the M2/M3/whatever supply) and think that it will improve the real conditions of the average (but especially lower class) American.
Never mind the foreign nations which credit the US which are obviously big losers every time a dollar is printed regardless of whether inflation occurs or not. Again, this is a proximate "win" for the US, but as we have seen, the foreign credit will rapidly dry up with these policies and/or the US dollar will lose its status as a reserve currency (China is already spending more on commodities and entering into bilateral trade agreements with other nations WITHOUT the dollar).
Call it the butterfly effect.
