If people have a bunch of money, inflation reduces the real value of their cash stash. So they end up worse off. So do people to whom debts are owed, since they get paid back in relatively cheaper money. On the other hand, people who don't have a lot of money don't take much of a hit. People who are in debt actually end up better off, since the real value of their debts declines. The more money you have, the more inflation hurts you, and if you have negative money, it helps you.
If you're rich and most of your wealth is in cash or bonds or something like that, your main asset -- money -- becomes less valuable in terms of the amount of poor people's labor it can buy. But if you're poor and your main asset is just your labor, that becomes more valuable in terms of the amount of rich people's money it can command. This is a progressive redistribution of real assets.
That's why I've gotten really into all this platinum coin stuff, and I'm eager to find new ways to make more money come into existence. If you can spend it on something good for poor people, all the better! But just for its own sake, supporting a higher rate of inflation (4% would be good) is something worth doing.
