Where is the money coming from to support that valuation? And why is it being spent to maintain that valuation? Part of it is accounting tricks (sell 5% of a company for $20, and you're worth $400 with only $20 changing hands) but there's also genuinely a massive unexplained amount of money in existence in the US financial system, that should have caused massive inflation by now but somehow hasn't. Maybe it's only a matter of time, or maybe due to class segregation, it's stable like this and will never come down the ladder to affect grocery prices?
Try harder to engage in dialog. Basic economic theory contradicts your claim. You need a much stronger logical argument to have any credibility.
More to the point: Congress is being profligate in other spending, and miserly w.r.t. science, so it does indeed look like the science cuts are not motivated by fiscal responsibility.
Your quip about "basic economic theory" doesn't really address the point they're making.
Wealth on the other hand....
If he dumped all of his shares the value of them would essentially go away, like with any commodity.
But specifically at this moment in time what you've written is total hogwash. Currently the US is spending money as if it's, specifically, an infinite resource.
Hence, this kaibosh on science funding can only be explained because the powers that be want it dead and gone.
Do with that info what you will. The various flavours of conspiracy-theory-leaning ideas on wanting to 'scare the scientist community away from commenting on political affairs' seem like the most likely explanation to me despite how petty and crazy that sounds.
If you are a scientist, get out.
Either out of science, or away from US-centric research systems.
