Although alcohol was illegal during prohibition, men and women that did not vote to ban alcohol still wanted to drink. It had become an addiction for many of them. Most married couples were either divorced or separated from each other over the issue of alcohol and alcoholism. Men would do anything just to get another bottle in their hand. When people started to realize that alcohol was a high demand, even after prohibition, they thought they could make money out of it. That's how people started to make their own alcohol to sell.
"Prohibition makes you want to cry into your beer and denies you the beer to cry into." -Don Marquis
