That's the difference between a corrupt and non-corrupt system rather than a capitalist vs socialist one. Nearly all European countries have an at least somewhat socialist healthcare system but in most you don't have to resort to those tactics.
the market / capitalism won’t correct itself, much people want to call it God/ perfect
Regulation, anti-trust laws try to correct somethings but many politicians are against those things because they limit the profit that can be made, profit first, that’s the corruption
