Oh, that's because they defraud government programs which provide grants to nonWhite immigrants to create "new" businesses. It all started with a single jeet named Patel buying a motel decades ago. Then he bought a few more and closed one so he could sell the assets to a family member who started a "new" motel using the government subsidy program. They give their family members paper loans - loans with no interest and no payment schedule. They moved on to laundromats, convenience stores, restaurants , basically anything cash based which can have less than rigorous financial records, and now international franchises such as chain restaurants. Import a new family member, close a business, the new one gets a grant, sell all the assets to them, share the profits.
I see Indian restaurants that no one ever goes to yet strangely they remain in business for years.
