“Life changing” money is relative. We take some family friends and their kids on a vacation every two years. Sometimes the bill is split, sometimes we cover most or all of the cost. We’re not rich, we just have extra money they don’t because of different life circumstances. But as a result we can help give them and their kids experiences they never would have had. Likewise some friends who are better off than we are were able to take us on a trip we could not have afforded on our own. Again they’re not rich, just a different set of life circumstances.

Now you might argue that “vacations” aren’t “life changing”, but I would certainly argue that if you never would have had the experience or seen the place then they absolutely can be. But even if not, I refer you back to the original thesis which is that “life changing” is relative. Because the sums of money we’re talking about would have been “pay my rent for a year”, “buy a reliable (used) car”, “reduce my student loan balance by nearly a third” sort of money. And those I think could all be reasonably said to be life changing sorts of things.

Finally I would suggest that if you are “throwing away” this sort of money on actually changing someone’s life, then you are by definition not “hoarding money” and can hardly be said to be poisoning society with your relative wealth.

Hoarding money is not economically prudent in a system designed with mild inflation. Money loses value sitting still, to grow wealth there has to be some action with a positive return. The trouble will billionaires is the oligopolizing of power and influence, not that they're sitting on gold that could otherwise be yours...

I've spent a lot of time in communities trying to grow past 'money' and decided that the usual replacement is allegiance to some other ideology that aligns everyone's incentives to a common cause or cult. I'd rather have diverse incentives with a common language of cash.

Wicked people will be wicked with or without money.
