The same shit happens in systems with more than two parties. You also have the problem to think about rallying behind the main party on the left or right side vs. one that is closer to your ideals but probably wont become part of the government coalition. In Germany, where i am from, we had 12 out of 16 years under Merkel with a “big coalition” of the conservative CDU and the social democrat SPD. All that happened was the SPD moving more and more to the right. Now we had a coalition that was supposedly progressive but collapsed hard as well as the Green party and liberal party FDP also moving strongly to the right. We now in 2024 have policies among the supposed center/center-left that used to be fringe far right by German standards. This is why voting “tactically” or for “the lesser evil” fails. It gives a false sense of what is demanded by the people.
Also for the narrative control just take the win of Biden in 2020 as a counter example. Despite Trump holding office the Dems managed to win.
So much this. In my country my parents generation could afford buying a house on two middle class incomes when they were end of 20s early 30s. In my generation that is only possible with generational wealth.
