It seems to be really important what people do with their additional savings. But I think the key point is that, most of the time, the person doing the saving is different from, and has different motives to, the person doing any investing. A highly complex financial system links the two. And in that system, there will be lots of opportunities for the additional savings to be parked as money.

Second, nominal interest rates cannot go below zero, and maybe we would need negative interest rates to persuade firms to raise investment enough. Does that mean the classical model is wrong?

Only if you think it applies at all times, and that there is no other reason why output cannot fall. However if we assume that the monetary authorities eventually are able to chose the right interest rate, then the classical model is fine when thinking about economies over a long enough time horizon. This all seems like common sense. Therefore, rather than talk about how people decide how much to consume, we will talk about how people determine how much to save.

Since income after taxes goes for either consumption or saving, it is a matter of twiddle dee or twiddle dum.
