Because capitalism is actually threatened by leftism, so the system actively suppresses it.

And I have no idea what should I be doing.

Imo:

1. Finding other people who feel the same way
2. Organizing/structuring your common discussion and research. I feel like I’ve seen 100 comment sections like this one where people see the problem, the commenters then speculate about the causes/solutions, and then the convo fizzles out without a deeper conclusion being reached. Every day under a new post, again and again. There is clearly manpower and a will to do something, it is just IMHO suffering from structurelesness. The conversation needs to be had once and thoroughly, in some central location that everyone can then be referred to. This way, people can specialize their research efforts, instead of everybody doing superficial research for themselves in isolation.

One centralized discussion I have seen is about the democratic side of the problem and it’s over at https://plurality.net/ (it is a crowd sourced work co-written using github). I think the political/economic side of the debate would benefit from piggybacking off of an existing centralized platform devoted to the cause, like https://generalstrikeus.com/ or some trade union.

There is nothing you can/could do. The endless war against intelligence and focus on just believing what some screaming asshole says on talk radio, combined with the dawn of the internet being weaponized to spread that brain rot, and here you go. Maybe if you can go back in time and murder Ronald Reagan before capitalism gets so out of hand that they can buy the government ¯\_(ツ)_/¯
