100 years ago:

Irish and blacks could only get menial jobs, if that.
Jim Crow was the law of the land south of Mason-Dixon.
Fewer than 1 in 10 minority children could read or write.
Robber barons had a stranglehold on the nation's business shipping, and could destroy any company they wanted by refusing to ship its goods.
Union strikes were broken up by security guards, usually by killing enough strikers that the others gave up.
There were few out-of-wedlock births because shotgun marriages were so frequent.
Prostitution was legal in many or most western states.
Women couldn't vote.
But they could, and did, smash bottles at bars and saloons, and would shortly lead the charge to Prohibition.
Blacks couldn't vote either, due to poll tax, voting "tests," and other disenfranchisement schemes.

Those weren't the days, my friends. It just depends on who's culling the data.
