Introduce land value tax.
In the countries using it, stop the mandatory Ponzi scheme retirement pyramid where young people are forced to pay a sizeable part of their paycheck while having no hope of receiving any in 30-40 years - that's straight up, time-delayed stealing.
Close the tax gaps used by corporations.
Provide free healthcare so people don't get ruined by medical emergencies.
Stop the student loan madness, provide free university education.
Restrict mortgage lending - it makes the property prices baloon in the long run and encourages housing bubbles.
Most importantly, start treating renewable energy and emissions seriously because we are destroying this planet with a speed with which we probably won't have to worry about economy after a few more generations.
Unfortunately, all of those would require enormous political changes and are impossible to implement.
