ELI5:Why do certain cultures consistently own in certain chains and establishments?

For example: Nail salons and dry cleaners often are staffed by asian individuals and Dunkin Donuts and 711 often have Indian staff. Not trying to be offensive when asking this question.

The reasoning behind it is mostly that people's families and friends help them get established when they move to a new country. Say you have an uncle with a couple convenience stores, maybe he'll give you a job in one. After a while maybe you save some money and buy a store of your own because you have lots of experience running one now, and an uncle who can help you find a good one to buy. 

A few years later you have a few stores, and your wife's cousin emigrates, so you set him up with a job managing one of your stores, and the cycle repeats.
