I don’t imagine organized crime would have become as powerful as they did though I’m sure they’d still be around.
Tobacco use was a popular American past time for many years before the temperance movement built up a lot of steam. There were some temperance groups that preached against tobacco though. I don’t know if Prohibition did anything about the popularity of tobacco one way or another.
That’s a tough nut to crack. If it’s a given that the U.S. never experimented with Prohibition then it’s a given that attitudes about drinking in the 1840s, 50s, 60s, and onward would have also been different. “What if” questions in history are fun little mental exercises but this is a question we can’t really answer.
We had a love/hate thing going on with alcohol back in the 19th century as well. Clearly a lot of Americans loved to drink but there were plenty of social problems attached to it. Men drinking away their paychecks before buying necessities for their family, domestic violence, violence in drinking establishments, etc. When they were building a railroad here in southern Arkansas after the Civil War construction came to a near halt the Monday after pay day as so many workers were sleeping off hangovers.
Maybe a little. When women in the U.S. started getting involved in politics it was typically in areas within the feminine sphere. Things like education, the welfare of children, taking care of the indigent, etc. The Temperance movement falls under this feminine sphere. I still think the women’s lib movement would have happened even without the temperance movement.
Bootleggers have always existed if for no other reason than to avoid paying those revenuers. As for NASCAR…maybe not.
