>So if you are a banker your social circle will be made mostly from your new coworkers and maybe maybe 1 or 2 childhood/college friends if they happen to still live near by. So you are much more likely to marry another banker, lawyer, trader and the likes simply because those are the people you interact with on your day to day, and those are the people you'll be more likely to see after work at less than official capacity. And if you're an engineer, you end up staying single because there's no women in your social circle at work.
