Signaling is, generally speaking, a means of displaying social status and desirability as a mate, yes?

If you can believe it, this claim isn't strong enough:

• you wear a suit to a job interview (otherwise you might be hard to work with)

• your bank spends a lot of money on impressive buildings (otherwise you wouldn't feel safe giving them your money)

• the government. The last three American presidents have been drug users who supported the War On Drugs. Otherwise, people would think they were soft on crime.
