Long term, this is probably the consequence. But to delete a giant tree (or tumour, decide your own mental image) you have to cut it back, then cut it down, then rip out the roots, one after the other.

You can also rip it out at once but you need giant machines and will cause tons of damage to the environment and leave a giant crater.

I dont think capitalism is even the whole tree. Its actually greed and selfishness which needs to go.

People who miss the basic empathy to take from others just because they can need to be educated and - if needed - contained and pathologized as to keep them from winning against the fair and „gullible“. This will be insanely complex and long to eradicate that.

But step one is joining a collective to change things. All positive change came from collectives, never from individuals. Individuals are easy to beat, to intimidate, to silence. But groups are very hard to do this to.

Doing something to lift the dread off your heart and getting change going is the most sane approach imo.
