Yeah but it's a prison of their (the americans') own making. In a one-party system you just don't have the option of voting for a different party, whereas Americans do have the possibility of voting something other than the democratic party or the republican party, but they just choose not to. From what I see the most common reason is that "if the republican/democratic party wins, America will become a fascist/communist regime, so even if I don't like this party I'll vote for it because the alternative is far worse", perpetrating the cycle of polarization.

It is the natural and unavoidable consequence of the plurality voting system (what we currently use). The only strategy reasonable to use if you don't have an ideal candidate in the race or they don't stand a chance of winning is to vote for the lesser of two evils that are likely to win. Change our voting system to Ranked Choice or Approval Voting systems and watch all of the alternative parties suddenly start winning races and the big two having to compete against them instead of just the other major party.
