It's just like mutation and evolution. I truly believe growth in homogeneous society will be severely limited. When you mix different ideas and perspectives together, you get stronger outcome.
Good for them!
Yes. Israel received top scientists from ex-soviet countries that helped to shape the country. Even in the pre-israel era, many people with science knowledge did agricultural jobs in search of an ideal.
If you are jewish it is straightforward to move to Israel, but it is a lot more complex to move to US legally. So, Israel received a lot of people from the diaspora giving them instantaneous citizenship plus economic incentives to move.
The main reason Korea isn't a startup hub is capital. Korean banks are incredibly conservative, they won't even lend money for cars or mortgages to most people. Capital is centralized and mainly allocated to existing projects or proven corporate models. Venture capital is non existent. Israel is the opposite of that with lots of investment and decentralized capital. In short, Israel has risk seeking investors, Korea doesn't.
When no one takes even low to moderate risks with money there cannot be a startup boom.

Korea is mostly homogeneous society and not very open to immigrants, and thus their growth is limited. So is Japan, and their growth also hit the wall as well.
I also agree on money. So true.
