How did people survive with Aspergers in the past?

I understand that autism and ASD were not as well understood in the past as they are now, but I am sure there were people who had it but didn't know it. In the past before there was the internet, social media, and dating apps, you had to meet people in person to form relationships. People would date and marry other people within their community such as school, church, their neighborhood, or work. It was expected that you move out of your parents' house by 18, find a good paying job, find somebody to marry, and have kids. If you were still living with your parents past 18, weren't married and had no kids by your early 20's, then you were viewed as if something was wrong with you. In today's world it is more socially acceptable to live with your parents past 18, not marry, and not have kids. Most Aspies are late bloomers. We may achieve those milestones later in life or not at all. It seems that there are more cases of autism today than there were 50, 60, and 70 years ago. If there were Aspies during those times then how did they cope in a world where it was expected to achieve milestones by certain ages?
