Comparing MLB to bar bands is probably not a fair comparison. Maybe major league musicians are more aligned? Compare Alex Rodriguez to Paul McCartney? Beyond that, it doesn’t all have to be so simplistic. I have never played in a band that actively promoted excess with alcohol, but obviously some patrons chose to drink more than I would advise. That’s up to them. And obviously the money I got paid ultimately came from the bar selling its product. You get to know the regulars. One of the positive things you can do is look out for them when they do over consume. Make sure they get home ok, don’t get taken advantage of, and so on. Perhaps you believe alcohol is evil, in which case of course you should not play bars. I drink, responsibly and in moderation. I don’t have a problem with others doing so. The difference between making love and masturbation is that making love is done in such a way that other people can be involved. Obviously a bar is not the only option for sharing your music, but sitting in your bedroom playing to yourself is a solitary act.
