It's not about the consumption of raw materials or repurposing of the raw materials used for chips. peterlk said:

It's about using the money for to build things that we actually need and that have more long term utility. No one expects someone with a 100M signing bonus at Meta to lay bricks, but that 100M could be used to buy a lot of bricks and pay a lot of brick layers to build hospitals.

I think it's a mistake to believe that this money would exist if it was to be spent on these things. The existence of money is largely derived from society scale intention, excitement or urgency. These hospitals, machine shops, etc, could not manifest the same amount of money unless packaged as an exciting society scale project by a charismatic and credible character. But AI, as an aggregate, has this pull and there are a few clear investment channels in which to pour this money. The money didn't need to exist yesterday, it can be created by pulling a loan from (ultimately) the Fed.

Seems like the main issue is that taxes in America are far too low.

I mean, you're just talking about spending money. Google isn't trying to build data centers for fun. These massive outlays are only there because the folks making them think they will make much more money than they spend.
