nah its social vs non social jobs if you notice.. the high divorce rate jobs are almost all jobs where people meet a decent amount of people on the daily. More exposure = higher chance of cheating or finding someone different. If you a scientist building satalites 8 hours a day you aint got time to cheat or find someone
but if you bartending youll meet 500 people tonight
a bartender can meet hundreds of people a night, some ugly, some attractive to them.. plus alcohol involved so people generally more social under these conditions, as with the gaming cage/service people. Basically 3 jobs where you are around alcohol all day and night and with people out having a good time.
Under these conditions people meet what they feel are upgrades to what they have at home.. rather its the vip girl who meets a NFL player or the bartender who meets a more attractive person than what they have at home
