If the US is the best at accommodating mobility impairments, that's got to count for something. Maybe it's not handling it well, but if it's the best than anywhere is doing, keep asking for better, but set reasonable expectations.

IMHO, there's a lot more room to improve accommodations for non-mobility impairments however, and there's examples of other countries doing better in some aspects to compare to. On-topic, accessibility of currency is clearly a US weakness, although the upcoming bill designs are supposed to address this, although we'll have to wait and feel if it works as announced.

Of course, disability rights and accessibility is a struggle for people all around the planet.
