For someone who’s Jewish you’re remarkably ignorant about the history of Jewish immigration to the U.S. and to Palestine and Israel during the late 19th century and first half of the 20th century.
The “aggressive risk takers” were (and are) exactly the kind of people who decided to uproot their lives, leave family support systems and guaranteed careers or marriages behind, and travel thousands of miles on little to no money to a completely alien country and culture. Risk-averse and passive people don’t do that – they stick with the bad they know.
The “aggressive risk takers” were the ones who avoided the purges and pogroms and the genocides of the 20th century because they pre-emptively said “f*ck this BS” and rolled the dice before things got worse. Risk-averse and passive people don’t do that – they stay put and hope for the best.
The “aggressive risk takers” who were immigrants who became American entrepreneurs who built brand-name corporations and entire industries from pocket change and pushcarts, and the Jewish ones became the people who built the modern state of Israel from a desert. Risk-averse and passive people don’t do that – given the choice, they prefer the job security of steady wage slavery and a country where they can get by despite not being considered citizens in full.
America is a successful immigrant nation because, from its colonial days, it wanted the aggressive risk takers. Same went for Israel before Likud and its Orthodox fundie allies decided that a religious ethnostate was the better choice.
