When I grew up in the 1950s and 1960s

It was very common to literally kick boys out of the house the moment they turned 18 and had finished high school and even before that at age 16 if they dropped out of high school. But, jobs were easier to get for anyone 15 or older then than now too. So, this just meant for a boy just getting any job to eat and to support yourself or joining the Army, Navy, Air Force, Marines or Coast Guard. Joining the military was a much more common solution in the 1950s and 1960s simply because all boys pretty much expected to get drafted anyway and have to go off to some crazy war and maybe die throughout the 1950s, 1960s and into the late 1970s.

For girls it was more common for girls 15 or older to find a man to support them or to get pregnant because remember abortions were not legal in the U.S. until 1973 with Roe Versus Wade. Another strange thing about all of this is the primary cause of sexual mores changing a lot during the 1960s for teenagers and college students was the "Birth Control Pill" which first became legal in 1960. When the Birth Control pill became legal people were freaking out all over from older generations and thinking this was awful because girls could now have sex without worrying about being married or getting pregnant. Venereal Diseases were not very common then for middle class or above people either so when a girl used a birth control pill condoms often weren't used until venereal diseases started to become more of a problem in the late 1970s and then during the 1980s AIDS killed millions of people around the world so this was the end of the sexual revolution first caused by the birth control pill in 1960.
