A country, or more than one, that enacted a program
to be a temporary or long term refuge for Americans might do themselves quite well if they have us spend our money there and contribute skills, start businesses etc. My suggestion would be that they also could enact a screening component about political views just like Crumb the 1st has done. Sauce both ways. There are already countries recruiting our students.
Additionally countries that don't feel they could take a large number of ex-pats could still be a welcoming haven for our bank assets. They could enact programs to attract Americans to switch their bank accounts and investment accounts over to the banks and firms in those countries. Your investments could stay the same they just wouldn't be on the books of US investment firms.
A large outflow of cash from the US banking system might get the fascists to understand that the people have more ways to fight than just holding demonstrations.
The point being that other countries around the world can, by creative thinking, turn things to their advantage as well as helping to blunt the American Fascists impact to their countries and give temporary haven to non-fascist Americans.
We can also change our purchasing to favor foreign companies even if we do remain in the US. You don't have to lease or purchase your vehicle through American banks, manufacturers etc. There are international financing and leasing companies for example and there are also international mortgage lenders as well. You don't have to use the US banks, mortgage lenders etc.
Decrease by as much as possible your purchasing of produce at the grocery store and make an effort to garden and/or buy from local small growers. If a supermarket chain sees even a 5% or so decline in produce sales don't think it won't get attention. You will also be healthier and the flavor difference of fresh or nearly fresh picked compared to what sat on a truck for a week or so will put a smile on your face. Also, for example, if the drive outside the city is possible you can usually find somebody raising chickens and selling eggs. You don't have to buy at the store all the time for everything.
The money people backing the fascists only respond to money increasing to them or decreasing from them. Decrease their money any way you can.
