agree, greater freedom of movement would force them to be more competitive & thus improve.
That freedom of movement I figure would need to come from a global constitution restricting nations right to force people to stay, or come.
An alternative would be smaller competing states. & because (actual) free trade allows open societies to out compete closed off societies the world would become more open.
the risk is that “bad” people can be shut out of the entire system (blacklisted) with no where else to go. Much like billions are shut out of the banking system now.
And bad is defined by the people in power. They may actually be bad people (eg murderers) or they may just be politically opposing those in power.
