Don't get me wrong. Not saying traditional nationalism is the superior way in all circumstances. But the globalism meme isn't working particularly well for anyone for anyone that isn't a wealthy, privileged university graduate with lots of money from daddy.
You don't have to go full nationalism to withdraw from a few policies that hurt more locals than they help.
Just hope that we get UBI in a decade or two - Don't get me wrong, i'd get flogged by lots of people who think like me for being a COMMIE but in that time we're also going to be rising to 20-30% unemployment in every 1st world nation due to mechanization of labor jobs thanks to robotics, so the easiest and safest thing to do is Universal Basic Income - Provide for everyone a single, monthly, stable amount of money with no ifs, ands or buts. Whether they have a job or not. Those who want can pursue and attempt to work in still existing jobs, those who don't can make things work and pursue hobbies and such.
People say this would be prohibitively expensive, but when you look at how much existing welfare costs now, it's not that much. UBI, preferably, would come along with the removal of traditional welfare for unemployment and disability. You wouldn't see people cheating the system - Taneesha will be getting the same amount of money, rather than getting more for every child she pops out. No incentive to try and cheat the system for more. Plus, you'd be cutting out the bureaucracy around welfare almost entirely, which would save money and government time.
UBI would by no means be a permanent solution - It has it's issues, as well. But it would provide a more static, less time-consuming alternative for Welfare that would address the growing, inevitable Unemployment crisis.
The end goal, of course, would be for more jobs to start cropping up again once we into space.
