I think it’s ok for everyone to pay something, and income tax is progressive.

Social security tax is regressive, and sales tax is regressive. So I’d remove the cap on social security, tax unearned income more, and exempt more necessary items from sales tax, if looking to get more from the more wealthy, as income tax is the only one working right - when I was poor my federal income tax was 0, when I was poor with kids I got a little more back than I paid in, now we are doing well, paying lots because we make more at work.
