Capitalism is not a tool that pays for social services. Its a system that allows private individuals to own the means of production (and along with those, the political systems, laws, and media of their domiciled countries) with the goal of extracting a profit from the sale of commodities produced by wage workers they employ.

Capitalists only apportion some of the surplus value stolen from workers to public services, when forced to by political agitation from below.

These proposals for ranked choice voting are a dead-end, because they already exist in many capitalist countries, and it doesn't fix anything. They just stack any number of candidates they like, and have their media push the most friendly ones.

If you allow capitalists to own production, then the political system will always be subservient to them, and be nothing but puppets to serve their interests. Anyways here's some more resources:
