Without nam, the USA would be so different
This is my speculation:
The flips and chinese who helped to build the railroads would still be living in their small groups like a china town and without expansion. All these souteast asian communities and what not in the USA would not exist.
The only southeast asian in America are those who are on a business trip or foreign exchange student programs but they too must go home after visa expires. There will not be enough of us to build any infrastructure
s here in the USA.
The whites will still fight with the Blacks for equal rights and the blacks will hold jobs that us Asians are having right now. Maybe by them holding jobs, they can at least equal out the playing fields with the white man.
South east asia will flourished like hong kong with sky scrapers all over the place and casinos built like macau. If our motherland was all that great, we don't need to go anywhere else.
There will probably not be any immigration act unless them mexicans are flooding on over and the immigration act is specifically for them. Remember that any immigration act for us Southeast asians, other nations can also piggy back it as well. They don't thank us though. They never do.
We wouldn't be here in America and I'll still be a farmer but with a wife and kids and good old country style living. Maybe uneducated and not knowing where the United State is on the map. I mean why would I even want to know about the America when life in our mainland is better?
