Nationalists are the elite's useful idiots.
You got that wrong. Globalists are the elite's useful idiots. How else could they undermine national labor and environmental laws by opening up free trade with nations that fall far below our standards, without the help of the useful globalist cheerleader idiots here at home?
Don't make me laugh. Why are labour and environmental standards being loosened and tax laws loosened? To "maintain international competitiveness". Of course if people jsinply united and pushed for proper global unity so that everybody in earth could enjoy the same standards with nowhere for megacorps to run. But no, that would make the flagmasturbaters weally sad so nationalists endorse the creation of a corporatist state with no standards at all. BUT MEH FLAG MEH COUNTRY MEH BORDERS
You live in a fantasy world if you think everyone would come together and set up universal labor and environmental standards acceptable to first world nations. It would be just as it is now, a race to the bottom. Nations that have low standards and authoritarian governments able to control their citizens will be the desired location of capitalists looking to exploit other people for larger profits. The only measures the rest of us have to fight against that is tariffs and subsidies, but the useful idiot globalists want to prevent us from using those measures.
What is needed is a new global trade bloc, with nations that meet minimum standards on human rights, workers rights, and environmental regulations that can enjoy free trade among themselves. Then slap tariffs on goods coming in from nations that don't meet those standards, with the severity of the tariffs proportional to the number of standards they fail to meet.
Eventually, way down the road when every nation has raised themselves to meet the standards necessary to join the free trade bloc, we can talk about your globalist utopia. Instead useful idiot globalists wanted to hurry up with their vision of some sort of Star Trek future utopia, without seeing that they were playing into the hands of capitalists looking for cheap labor and lax regulations to exploit. And you ended up hurting the working people in your own countries in the process.
