> Creating more money reduces the value of money that already exists.Yes, which is why all the people who don't get any of the newly created money lose wealth. They have the same amount of money as before, but it's worth less.
Where does the wealth they lose go? To the people who did get the newly created money. In other words, it's a wealth transfer from whoever doesn't get the newly created money, to whoever does. Usually the latter are banks and financial institutions, i.e., the rich.
> It helps those who are heavily indebted
As long as debts are denominated in dollars, yes, the real cost of the debt is reduced. But the people who don't get any newly created money also lose buying power, and the latter loss is not fully compensated for by the reduction in the real cost of their debt.
To see why, consider a simple example: I have $1000 in monthly income, $200 of which goes to pay off debt. The government creates some more money but I don't get any of it. The dollars I have to spend on debt each month stays the same, $200, but it now represents less real cost than before, so yes, the real cost of my debt has gone down. But the dollars I have left over for everything else also stays the same: it was $800 before and it's $800 after. But the $800 now buys me less than it did before, so in real terms I am still worse off.
> The savers are losers, regardless of net worth
Assuming they don't get any of the newly created money, yes.
