Very true,but the point is "where is the money coming from?".
From my experience, it comes from them (a) buying a chunk of property with what cash they've accumulated in the old country and (b) leveraging it to the hilt.
In the old days, immigrant shopkeepers and innkeepers were amazingly poor, especially when they started out. That's because they put every last penny they had into the business.
Gosh, ain't it just EMBARRASSING to get shown up by some immigrant who's willing to hold off on the his and her's Lexuses, the SUV, and the expensive house?
