I am not so optimistic. A globalized world with free movement of people and workers seems further away then ever, and if anything we are moving further away from that world every year. The very same politicians that help facilitate the free flow of capital and exploitation are at the same time pumping up xenophobia and advocating for closed borders. The border walls are coming up both a literal one in America and a tech dystopia one in Europe.
China is getting more rich, that is true, and workers in China are not living in the same abject poverty they were in the 1980s, but labor rights in China have not improved much, and neither has consumer rights. And even if by some miracle the next General Secretary of the Chinese Communist party is a socialist that enacts labor rights and consumer protection across all of China, making exploitation just that much more expensive for capitalist exploiters, there are other labor markets which are unlikely to get such reforms, particularly in India and West Africa. Also the borders into China are not exactly open either.
Yes it will be annoying for the capitalist class, but they will absolutely do it, if it means more profits, and they will lobby governments to keep borders closed, to shut down any potential for free movement of workers, and global solidarity.
There is a reason why a popular slogan among unions is: “No free movement of capital, without free movement of people!”
EDIT: Thought of an example to back up my case. Within the EU the free movement of people was inseparable from the free movement of capital from the start. This has been a great success. On the contrary, NAFTA had only the free movement of goods and services and capital, but neglected the free movement of people. Allowing free movement of people was hardly even discussed, and after 9/11 there was no way it was ever going to realize. Now NAFTA is dead. True globalization was, in fact, not inevitable it turns out.
