An asset appreciating in value does not deprive anyone else of money in their wallet.
If you bought a rookie baseball card for $5, the player had a great year and now the card’s worth $100, your net worth increased by $95. But who is down $95 as a result of your card becoming more valuable?
Nobody. Wealth is not zero sum. And the vast majority of increases in wealth among the wealthiest is newly-created wealth. You literally can’t become a billionaire in a human lifetime simply by short-changing your workers. A linear increase like that just will not get you there.
Also, wealth in the form of purchased investments into businesses that run within the economy, is literally the opposite of hoarding. If you buy things with your money, you’re not hoarding your money.
$10k would definitely not make me stop caring about whether I lose my job, lol.
