This is what globalism does. Take the environmental destruction and shitty working conditions that would never be allowed in your own country to other countries and centralize the profits from doing so into the hands of a few.
Globalism permits to all countries around the globe to develop.
Nobody is preventing these countries to set laws about environment and working condition (which they actually do).
And by the way, I invite you to go to these countries and visit the factories there, and you will realize that western companies are raising standards (security and quality) on their suppliers.
What he said, by implication, was "read a book on macroeconomics".
There's absolutely a big push to keep employment laws as well as other laws „flexible“. And keep salaries as low as realistically possible. Otherwise MUH INVESTORS will go somewhere else. To be fair, it's not (just) foreign investors. Local elite is making $$$ providing support to incoming companies. Real estate moguls, construction companies, subcontractors etc.
Ultimately it is a race to the bottom to appease the sacred investor and let local elite enrich themselves.
He was wrong though, it appears, no? I mean one could argue that there would be more wars without globalism (I'd counter argue there would be less weapons) but one cannot say "globalism prevents wars" in general.
