This is one thing I think America has done right, the ADA is so nice for people with disabilities. I want everyone to be able to experience everything so having the ADA being strong is perfectly okay with me. And I think both sides agree, everyone will get old someday!
Bear in mind, this is relatively recent in the US too. It's culturally connected with both the civil rights movement of the 1950s-1960s, and to the respect that Americans (sometimes) express for war veterans.
