I'm glad you asked, here is my proposal.

1. Execute Elon Musk and nationalize his wealth. This puts the fear into the rest of those scumbags, keep them on their toes.
2. Time to raise the graduated tax brackets, something like 90% on income above $5 million. I just made up that number but I'm not a policy analyst, just a humble douchebag.
3. Double the capital gains tax.
4. 15% on unrealized gains above some threshold.
5. Incredibly high tax on properties that are not owner occupied, I have a personal vendetta against landlords so fuck em.

At any rate I'm still being more helpful than your "can't afford it" rhetoric.
