Why does everyone on the right always read "not totally free economy" as "planned economy".

Regulate the markets. Have the government own natural monopolies. Have large government sellers and buyers in all markets. Break up monopolies. Ban harmful products and services. Ban marketing to children. Ban dishonest marketing. Ban planned obsolescence. Increase the capital gains tax to companies are incentivized to invest in production rather than pay out dividends. Ban stock buybacks. Have CEOs be personally responsible for crimes (remove the LL from LLC).

Those are good places to start.
