"Built to make people's lives worse" is an opinion. There are people who gamble without getting addicted and treat it as good fun. Why shouldn't I be able to bet a small amount on a team I like in Fantasy Football? I've never gambled more than I could afford to lose nor have I felt the need to do it habitually. I get that there are some people who are not like me, but you seem to think that there are only people who are not like me that use these types of services.

There's a difference between betting between your friends on FF versus creating a system of gambling that takes advantage of the least fortunate among us.
