jones Capitalists were always dickheads in great measure.
Here's what I reckon. Holders of capital in the OECD supported high nett migration prior to globalisation because it helped them suppress domestic wages for their fungible workers.
In the present era, people in Musk's position have far less material interest in domestic migration or social cohesion. Most of their supply chains are offshore. But on the other hand, if such people use their influence to generate conflictual and chaotic politics in the states in which they're selling as opposed to producing (in Musk's case, wealthy countries), then they've got a better shot at obtaining governments which succumb to their lobbying for the reckless deregulation of their activity.
One can imagine why Musk, an owner of financial, car manufacturing, space, AI, transport and neural interface businesses would love an economic libertarian regime in place in the US. And as far as migration goes, the policy pull of US technology R&D capital continues to allow him to cherry pick his technical lieutenants and managers.
Generalise the concept, and it gives a plausible theory of why today's billionaires who pay wages in poor countries and sell product in rich ones are often damaging trolls or supporters of fascism. It's because they've always been awful, but now there's fewer economic incentives restraining them.
