And it's a very tenuous dream at that, I'd say. It requires constant handholding, upkeep, juggling, whatever you want to call it, to manage all of the visas, plane tickets, bookings, finding remote work, finding a network of people for which reason you allegedly moved to the country :)
Call me square but it's much easier to just overpay for rent in the USA and just focus on building "bulletproof" skills for a long career here.
After all, nobody stands up postgres on EC2 anymore right, we all just use redshift and lambdas? right? ok well maybe not all of us :)
People buy into the dream.
