Bringing health care costs and education costs in line with historical norms is hardly adopting the worst aspects of European countries. We can still treat immigrants with respect and grow as a country even if we experience some changes.
If anything, having a basic level of insurance that’s portable between states by default would encourage more people to leave established companies and found startups and small businesses.
Lowering education costs so that anyone who qualifies can “work” their way through college would also increase economic mobility.
No one. Literally NO ONE is suggesting that we adopt the system of nepotism that exists in some countries outside of the US.
