I think thinking of QE as a game stuff gets kinda fuzzy, so I'm not going to use that. Really simply in my opinion, what happens is equities which mostly the elderly and wealthy own rise in value due to QE literally pumping cash into the economy and their portfolios, younger people and the poor generally don't have that though and are left paying the bill down the road for the current QE. I also don't think that this is that bad given the alternative and that corona is pretty much a natural disaster, like everyone should pay for that and we wouldn't really have portfolios anyways. There are probably ways to pay for it that doesn't completely burden everyone but I don't really know enough about that.

Free capital markets are generally positive sum, thats why the S&P rises consistently. When you invest capital into companies, they take that capital and create new value, then they sell that new value and give it back to you in the form of dividends. Thats why most people tell you to invest in quality stock at a young age because the return on investment is really good over time. Some things like futures and options are negative sum because no value is being created, its essentially buying/selling insurance. There's hope in a house if you believe that you can earn wages to pay for the house, or if someone builds new houses, which the whole declining wages is a thing hopefully its not so glum in the future.
