Is believing people should have a choice a moral high ground now?
No, but believing our so-called "democracy" (quotes intended, read: "21st century western systems") is how you give people "a choice" is the moral high ground. That is your axiom, but it's often touted as a tautology.
The name says "demos" and "kratos" but names are names, not facts.
There are many ways to give people a choice and this one has proven to be quite ineffective at that, as it slowly devolved into a plutocracy/oligarchy. Iron law of oligarchy, yadda yadda.
What they are very effective at though: crushing dissent, calming the masses with a reassuring illusion of choice, and touting itself as the "one true way".
When I look at the outcomes I don't see any semblance of democracy, only a ritual dance/theatre show every 4 years. A farce as big as the "democratic" instruments on the PRC.
There's a reason this "democracy" is very diligent at discouraging association and unionizing. Those give actual power to the people (and with power comes choice). That's dangerous. People might start believing they can actually influence the outcomes.

You have a 2 party system where on many fronts both parties tow (almost) the same line and roughly behave like a oneparty system.
