The main feature of capitalism is not free markets, it's capital. And capital accumulates leading to inequality that only ever gets bigger unless we actively take steps against it as a society. Being against monopolies doesn't help if you're not willing to actually punish them.

Free markets are great but to really work they need to come with competition enforcement (including total M&A bans in high risk industries), strong unions, support for worker ownership and a tax structure that rewards productive investment instead of executive payouts. Market socialism instead of capitalism.
