Add winner takes all elections to this list. It always leads to a shitty two party system, exhibit a being the USA. Instead, have elections with 30 parties, each having a little bit of power, that have to work together. It gives people a chance to actually vote for the person they want, it stops the extreme swinging to left and right each time an election is won by the other side.

Add 100% income tax for those with a net worth over a certain amount, say 1 billion or so. If at some point you have souch money that you can impossibly spend it in your life time, you don't need to have it. Need investors? Make non profit investment funds, financed by the government taxes.

Add 100% gains tax for companies that have grown beyond a certain amount of employees. No extremely large company with 80.000 workers is a nice place to work at, they guaranteed fuck over the employees and customers because that's what they do. Simply cap companies on how big they can be.

Extending the previous one: prohibit companies from buying other companies. It always ends up stifling the competition, it pushes companies that wholly exist for being bought, nothing else, it's not healthy.
