I mean, that is the essence of how to fix the problems in a capitalist society?

One of the core tenets of capitalism is that one person's profits are another person's opportunity. If the latter can do the work/obtain the capital to break into the industry, they can capture some of those profits by offering competition at a lower price point.

I don't think the person you're bagging on is saying it's easy to do; but they are saying that if people feel strongly about changing something, perhaps they should try doing it themselves, instead of just complaining about it and wishing someone else (i.e. government) will fix it for them

So... we're just gonna forget that governments exist?

We gonna assume rivers would've stopped burning in the US if only there had just been more startups working on making rivers stop burning?
