> In the last major economic recession, that's 2008, many fortune 500 companies were built.

I didn't know this, but it makes a lot of sense. 

>I think it's because these companies give people hope that everything is not going to end.

The other thing is, it gives incentive for the employees, as they are able to possibly get in low to their company, attaching them more. plus, they get to feel a part of building better - they get that sense of accomplishment and ownership.

>During a bull run, everyone is smart. During a bear market, you find out who's smart.

Absolutely.
