Earlier quoted context omitted.
I mostly agree; the only caveat I'd give is that it's tough to say how much longer any of us are going to be yuppies right now; I work for one of the many big megacorporations whose stock is tanking right now. If the stock doesn't pick up soonish, there's a non-zero probability of me being laid off. While I'm not that worried (I've been able to find work in bad economies in the past), I also do feel a bit of paranoia…
Why? The price of the stocks does not affect company in any way. If the company sales are going down or clients stop coming this is an issue, stock value is important only for those who hold/speculate using them. You company has already got the money from selling stocks, nobody is going to take them away.
Since the market is tanking, there's a likelihood that people will be spending less, thus leading to less profits for my company; as a result, the only easy way to keep investors happy is to reduce costs, and the easiest way to do that is to start doing layoffs.
