The US and China should invest in their own fabs and become less dependent upon TSMC (which is happening and even if both dumped enormous funds into this it would take quite a long time to overtake TSMC. Which is why China is doing this in the first place).
in the software world, I've seen this happen and the salaries never get rolled back. So it will have to be sustainable...
Considering the geopolitical situation we could interpret this as an attack and defense (economic warfare). TSMC is Taiwan's most important industry and is one of the reasons the West helps protect them (besides the military advantage of location). China has long said that Taiwan is not a sovereign nation and rather a rebellious territory that is acting illegally. What we're seeing is part of a war going on, not two companies competing (TSMC vs SMIC).
How is two companies companies different from economic war?
Are two companies fighting or are two governments? If I'm the government and hand you ten million dollars and say "hey, go poach some employees from that strategically valuable company that is in the country of my enemy."
I'm not sure what part you aren't getting. That the government is handing SMIC cash? Because I said that three times now.
Moving was obvious? Somehow, amazon manages to stay in business.
This is just owners not wanting to reduce their share of the revenues
As for point 2, TSMC's financials are public. They spend ~30 million a year on payroll. On the other hand they expect to invest a total of 100 billion into their next generation fab over the next 3 years. The idea that penny pinching salary is what enables their capital spend is hilariously out of touch with the scale of the relative expenses.
This could be ONCE IN A LIFETIME career jump, using national security as a reason to deny employees’ career development and salaries negotiation doesn’t seem fair.
I'd expect 5-10 billion in salary based on your description
