You're mixing up your terms here. A recession is simply a prolonged period of negative economic growth. It can happen with or without more money being added to the system.
Using the definition you've extended here, the early 90s economic recession was not an economic recession because Bush Snr didn't print money.
Never said it did. However, conversely, increased productivity does not, contrary to libertarian economics, always lead to increased prosperity.
While hyper inflation is not characteristic of inflation, generally high levels of inflation hit the middle hardest, since the poorest sector of society's main asset is their wages, and wages can adjust for inflation while savings can't. The rich usually have most of their money in assets or investments and relatively slight liquid holdings, so, again, they're not vulnerable to inflation.
But this is missing the point - contrary to what you've written above, inflation is not exclusively caused by wealth distribution. Periods of high economic growth are usually accompanied by spikes of inflation regardless of whether or not that growth was state simulated or privately simulated. Redistribution, ironically, only creates inflation if it does its job, e.g. by creating economic growth.
Once again a caricature of Keynesian economics. Nobody would argue that simply printing money in and of itself will increase wealth. The argument is that printing money is a necessary evil for spending projects that will create sufficient economic growth to outweigh the inflationary effects of the printing. It's the same logic as a business borrowing money in order to expand, except that the state's method for increasing liquidity is different (although states often do borrow, and in fact generally prefer to do so).
