That's more the stock market than the US government though. You could argue the US government tries to play a long game, and often the way the US plays that game is to let the free market decide (hands off, small government). It's definitely a valid strategy and has worked extremely well in a number of other industries, but for this specific niche, less so, and even then you could argue it's down to Intel's mismanagement than anything the government could or should have done.
I can't make the argument that the government is "hands off, small government" because I simply don't see the evidence of that. To the contrary, I have seen things like TARP, stimulus checks, oh, and the government buying 10% of Intel.
I don’t think propping up Intel is going to work though, they’re a sinking ship and their management seems too risk averse and incompetent. It might be better for the US, long term, to let them collapse and sell off strategic parts to different domestic players (NVIDIA, AMD, micron, TI, etc) and use tariffs or other trade policy to force some amount of leading edge semi fabrication to use domestic manufacturing.
Just as an example, the calculus for "where should I build a factory" comes down to "which politicians give the biggest tax incentives" and not any market dynamics.
It's a side effect of systemically putting short term gains ahead of long term research. CHIPs act may be too little, it is certainly too late...
