I am a libertarian and I am for free movement of labor and capital. Even open borders. But that it incompatible with a welfare state because you end up inviting people who just want to benefits. Not sustainable.I know this. But libertarianism doesn't match with a policy of closed borders. If you value competitiveness, you shouldn't be protectionist. Moreover, if you're a libertarian, you shouldn't care if money is made in China or USA, considering that citizens from both countries could migrate freely.
