State corporations exist in Western countries, and Western governments do focus stimulus on industry-wide sectors of the economy, and subsidize research of novel technologies, but that is different from owning a stake in a private company, and dictating what it should do. Donald Trump knows nothing about semiconductors, or computers. There is a reason why market economies are more efficient, because the bureaucrats back off knowing they have no expertise in anything. Donald Trump has the instincts of a dictator of a planned economy, in that he wants to force things, instead of conceding to reality. This is why planned economies are very inefficient or how planned regimes created famine, because they wanted to force the economy into something it is not.
They should have done things like this some time ago, instead of nationalizing oil companies.
This happens in Mexico too. People are tired of foreigners coming in, and snatching up scarce resources like housing, driving up the costs for everyone else. Australia has some of the highest housing costs in the world. This is liberal policy blowback.
Planned economies are not efficient. The problem is using money to prop up a failing company. Why does a failing company get propped up while others who have better products get less help? This is anti-meritocratic, and would be considered corrupt, as we see it in other economies. Intel is not strategic, it is a failing company with inferior products with NVIDIA, and AMD gaining market share. TSMC is a Taiwanese company, not a Chinese company. Taiwan is not a rival, and certainly not a peer competitor. If anything, Taiwan has been instrumental in the US economy, which is why Biden passed economic incentives to onshore TSMC production in Arizona. Capitalism is the survival of the fittest, the prosperity of the best. Propping up Intel is neither strategic nor economically sound. It seems that Trump is responding by his nationalistic impulses than thinking things through.
You don't like the better option. Beggars can't be choosers.
Intel is losing to competition. Other companies produce better chips.
Don't use it. Be smart.
