The consequences are supposed to be inflation. Instead, we seem to only get asset inflation (houses, stocks) and not consumer goods inflation (flour). From a former econ prof who I spoke to recently: the central bankers aren't thinking about inequality or inflation right now, they're just trying to avoid the apocalypse.
The liquidity injected is supposed to be taken out later, thus removing the inflationary distortion. Whether it will or not is anyone's guess. 2008's injections have yet to be taken out.
Central banks are easier creditors because, while autonomous, they are the same country as the government! So it's technically like owing yourself money. A central bank that cooperates with the debtor country (itself) would never force a default, and is thus never an acute problem. Of course, infinite money printing should lead to dangerous inflation.
