Competing to have the public want you to represent them. How is that not competition? Competing to have a greater majority consider you a viable representative.
This is competition between politicians within one government. Not competition between governments for citizens.
True. For governments to compete for citizens requires freedom of movement. Living standards and job opportunities would be how they would compete then.
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.
