Its too bad much of History isnt taught
In the Late 1800’s there was a massive Catholic immigration into the US and the Protestant population didnt like it. The Catholics preferred their own school system to the existing public School.
The Protestants then passed constitutional amendments in most states including NY and NJ prohibiting taxpayer dollars to going to religious schools (But they really meant Catholic, but it applied to all religious Schools) These amendments are called Blaine Amendments and its the reason today vouches for yeshivas are illegal in most states (The amendments said religious schools, not catholic Schools)
I am sure you heard stories of people being forced to work on Shabbos and if they did not they were fired. It was the unions in the 1930’s especially that pushed for the 5 day work week inadvertantly allowing Shabbos observerance much easier as most jobs did not require you to work on Saturday (Or Sunday for that matter) anymore.
In the 1960’s there was the civil rights movement and while the African Americans, Alternative Lifystyles, Hispanics and other demanding their rights, it turned out Jews also got their rights as well. No longer were Jews barred from most places. Jews were pretty much free to do as they pleased, Live where they want, vacation where they want etc. The American Charedi lifestyle would not be possible without the civil rights movement
