We can always find something to justify putting on airs of superiority, but the fact remains that our infrastructure stagnates while the rest of the world manages to modernize. Forget the China comparisons if they are so triggering. Europe still manages public works. Individual rights have to give at some point for the good of society.
Start? The entire labor movement, the public accommodation portion of the civil rights movement, and the rest of the transition from gilded age capitalism to the modern mixed economy has been a process of reexamination of and evolutionary progress from the classic capitalist conception of properry rights. Just as, for that matter, the several centuries of evolution from feudalism and other pre-capitalist economic systems through Enlightenment liberalism to the peak of gilded age capitalism was such a reexamination of pre-capitalist ideas of property rights. And while you can conceptualize them roughly as successive and mobotonic, both of those are oversimplifications; elements of pre-capitalist patronage-oriented systems were still around past the peak of capitalism, and isolated points of reversions from capitalism to them or to purer capitalist models from their replacements occurred throughout the process and still do.
But the idea that society is sitting on some static foundation of property rights that is waiting for a beginning of a reexamination is...not remotely tenable.
(1) painfully slowly, or
(2) catastrophically, with massive bloodshed.
And while #2 often produces more rapid change considered over a short term, it also tends to be less secure change subject to equally rapid and equally bloody reversal.
It's frustrating, but I’m not convinced its solvable.
