There has never been 'an excess of RAM', the market has always absorbed what was available.

Yeah right, tell that to Qimonda.

Sell it at lower prices. Demand is a function of price, not a scalar.

Tax write-off donations to schools and non-profits, too.

I suspect there will be a shortage of something else then…

And regardless, you could flip it around and ask, what will we do in x years when the next shortage comes along and we have no fabs? (And that shortage of course could well be an imposed one from an unfriendly nation.)
