It’s by design. Divide and conquer Combine and conquer has been the playbook since they (anti-labor think tanks like the Progressive Policy Institute and others that seek to keep labor infighting) started studying group psychology.

Literally, if there are only two private parties run by private organizations of rich people, they merely have to divide us and conquer us. We are being puppeteered by a bunch of corporations that use identity politics to keep the poor fighting amongst themselves and people SLURP THAT SHIT UP BECAUSE THE TWO PARTY SYSTEM CODIFIES IT INTO EVERY DECISION.
Feudalism with a few more steps.
Interesting point, though and I can see what you mean.
Truly, if my comment were to make sense, I’d have to say they have “combined” and conquered.
