Probably leave religion in the past, recognize the oligarchy as the source of most of our woes, legislate for a maximum income, laws to make home ownership by companies illegal, begin providing universal basic income, stop caring about the boarder and just let people in, decriminalize drugs and prostitution, criminalize bribes to politicians, break up the obvious monopolies, nationalize internet access, expand voter access and encourage everyone to vote, release prisoners from prison for non-violent offenses, close private prisons and reform tge whole court system, structure fines for laws broken as a percentage of income making them a deterent even for tge wealthy, ties minimum wage to inflation or tge gdp in some way so it can keep up without further legislation, open a new department that is not police to handle most calls more ethically, cap income within a company so no one can make more than X times more than any other employee of the company, simplify tge tax codes to close most loopholes, empower tge IRS to send citizens a bill instead of paying turbo tax, prevent civil forfeture, remove state ability to fine individuals without an income for not paying fees, expand disability benefits so you can have more than $3k in liquid assets and still get benefits, and so on.

These were all just off the top of my head.
