Sometimes it looks as if it matters more whether people are good and work in good faith rather than what a particular system is.
However, the more extreme the system (be it anarchocapitalism or communism), the higher the requirement to the goodness of people.
As is, in current societes I find that the ambient chaos of general democratic capitalism counteracts the threat of small minority making wrong decisions (Mao’s famine, etc.) while strategic regulations help curb bad actors abusing the system (like selling people poison or dumping toxic waste into rivers).
Both are needed, and I usually suspect that people who call for one extreme or the other either have an agenda or have not thought it through. (In the West it is often pro-capitalist tendencies, though I encountered both.)
Only liberals could describe our system as "democratic capitalism" with a straight face, its absurd. I'm on the left, I'm not a liberal, so no, we are definitely not on the same side. I believe our intolerable levels of inequality and disparity is caused by systemic issues not some "bad actors".
