Ah of course, the “everything I hear about is bad” bias.
There’s an insane amount of small businesses out there, have a look at your friendly government’s statostics.
You know how these small businesses start? Often by telling friends and family about them (marketing), posting ads on the local notice board (marketing), having a damn logo on the door (marketing).
People have to know you exist, else they can only come across your shop by mistake, and no way you’re surviving a week like that.
All of these places would fail without any sort of marketing. Concentrating the power into the hands of established players.
Whatever you stand for, it doesn’t work.
The world is capitalist and it’s not changing anytime soon.
Meaning, whatever your ideology is, it’s a waste of your and everyone elses time.
Adapt it to reality and push for smaller changes, a big one ain’t happening.
