Why does America stick to a bipartisan approach to democracy?

I ask myself this every day. The answer I think is that the two parties hold the reins of power and don’t want competition.

Because all of our elections select one candidate each and each person gets exactly one vote. If a third party runs in that system and gains serious ground, they'll just split up the vote, screw over the candidate they're more similar to, and possibly trigger some undemocratic contingency. There's really no way to have more parties without changing the voting system to ranked choice, parliamentary, or something along those lines.

We would have to switch election types. Our current style is dominated by the two corporations (sorry... parties).

Tradition has its own inertia, especially when it wields power because it resists change. Our two-party system is not enshrined in the constitution and it makes little sense to me. The fastest growing voting block in the USA are those unaffiliated with either of the two major parties.
