Yes, I think there were more institutions and custodial schools back then and before the Americans with disabilities act around 1980, people with disabilities just didn't have as much access to public spaces.

In the 1970s there was a movement called &lt;Deinstitutionalization&gt;. 

That’s where MH advocates decided to discharge patients from state hospitals and various asylums to give them more “freedom”. 

However, there was no supportive housing (staffed) or infrastructure built for them.

This has (partly) contributed to &lt;the homeless situation&gt; we see today. 💔💔💔💔
