There is no such thing as 'a person's purchasing power'. Please ignore that - sorry.
This statement totally baffles me. A person's purchasing power is equal to their spendable income times the purchasing power the dollar. If a dollar has a purchasing power of
n, and I have $500 that I can spend, my purchasing power is 500
n. The statement that there's no such thing as an individual's purchasing power is literally mathematically disprovable. If you can assign purchasing power to a dollar, you can assign it to a person based on the number of dollars they are able to spend. That amount is limited by exactly two things: how many dollars they have, and how many dollars worth of goods they are willing to purchase.
All of the money that doesn't go into the "goods I'm willing to purchase" pile goes into other piles, and contrary to your repeated ill-informed arguments,
several of those other piles don't contribute to the economy. The "money I've put into offshore investments" pile is often massive. The "money that's being stored in offshore bank accounts" pile doesn't contribute to the US economy, and it's a big goddamn pile, especially if you're very wealthy. The "money that is being stored in offshore trusts for my grandchildren" pile would startle you, and it doesn't contribute to the US economy, either.
What I meant was: because wealth redistribution does not introduce additional wealth into a system, the increase in a person's wealth must be balanced by an equivalent decrease in someone else's wealth.
Already acknowledged, but still irrelevant. Wealth redistribution doesn't introduce additional wealth to a system, but that's not the point. The point is to introduce additional
economic activity into a system that has stopped (or dramatically slowed) growing. But there's actually another point to be made here: when the economy grows, everyone benefits. Even the wealthy. They might have less absolute wealth in the short-term, but when the economy is growing, they benefit more than anyone else from all of the new inventions and services that an active capitalist market comes up with. So there's actual incentive for wealthy people to
want to redistribute wealth: it will give them fun new things to spend their money on. The wealthy in the US are simply too short-term oriented to think that far ahead. Literally, for them, it's better to have an extra never-to-be-used zero on their bank account than it is to have cool shit. And that's a problem.
The PDF document describes how new money is created. It does not imply that whatever money goes into banks exits the economic system.
Dude, are you brain-dead? If money is sitting somewhere and it's not being used for anything, what is it other than
not participating in the economy? If nobody is borrowing the money from the banks, that money is, for all intents and purposes, nonexistent. It's not contributing to the GDP. It's not growing anyone any wealth anywhere. It's dead to the world.
In fact, the fact that banks create money by lending rather than relying on existing deposits takes that a step further and completely annihilates your argument that rich people's money that's sitting around in bank accounts is actually participating in the economy
at all, ever. If the banks don't need those deposits in order to lend, and lending is what stimulates growth,
the banks don't need rich people to stimulate growth.Money in the hands of rich people who can't spend all that they have is literally completely functionless. It's a waste. The banks don't invest it, so it's not helping anyone anywhere. It's sitting there being zeros on a screen and making some rich person feel rich.
