personally, these last few years have shown to me that globalism in any form is cancer. capitalism? very good economic system to allow for the free trade of goods and services, builds a strong nation that is able to grow different needs for the citizens as required. global capitalism? shitshow that relies on slave class that doesn't get to participate in the free trade and nations that would collapse if cut off from the market due to natural factors that can't be controlled on a global scale. relies on the idea that each nation and their peoples can provide adequate resources to supply themselves and others plus leads to nations relying on foreign supply/demand which has lead to several problems in the past few decades. a nation should be self sufficient first before they can even think about trying to breach a global market, becoming reliant on exports or imports is a recipe for disaster.  and the argument of productivity is a crapshoot since even if you have more people due to unguarded borders, it does not equate to more being made as is the case in america, all it is doing currently is devaluing the labour of current citizens for the benefit of people who do not belong, circling money back to their original nation due to family rather than circling it back into the nation's economy (got to look up the statistic for this, came across a couple of studies that rocked my world view with how many of these people do not view their host nation as their nation).
