Is bootstrapping something only for immigrants?

Bootstrapping a company is, in my opinion, a challenging but secure way to go about building a startup. And yet very few people do bootstrap. Those who do typically have migratory backgrounds – they know from family experience what it takes to 'start over'. Or perhaps it's engrained in cultural and upbringing mentality, to keep the balance books in order from the beginning onward. Or perhaps the consciousness on how much you personally are willing to risk, and knowing the importance of holding onto control over your vision as opposed to having to cater to backers desires. Whatever the case may be, I do wonder why culturally native people in western societies rarely consider bootstrapping as a reasonable option to launching their business.
