The wealthy are the landlords, the employers, and the provider of goods and services for sale though. You go after them, they have to make up for it so they raise prices and rent and make some goods smaller but charge more.
They tried this here with a proposition that made anyone making over 500k pay even more. Suddenly rents went up, mortgages went up, goods went up, services went up, and people were thinking that it was the rich being greedy. lol, nope, they were the ones wanting this redistribution were the sole ones responsible for it.
Ease up the taxes if you want prices down. Give them tax break incentives if the taxes go down and cost of living is reduced by them and make it to qualify they have to prove how they went about reducing things in monetary values.
Problem solve this instead of using the tax the rich BS. Over taxing is what's causing this, it ain't going to make the costs go down and anyone who tries to lie otherwise is again, LYING. I'm not even an economics major and even I can tell you how simple it really is.
