Ask around, and you will find out that most of them are family members of the owner (kids, in-laws, cousins, niece/nephew).
Family works cheaper and you can pay them off the books (no taxes and such), thus keeping overhead lower and profits higher.
How do I know? My cousin and her husband worked for his folks in one of their stores (no, they aren't Indian). Most of their wages were cash, and they lived in an apartment under the store (free security). They worked their way through college with those jobs (he, a lawyer; she, an ICU nurse).
