Some do. Anyone with control of a phone system with digital lines (i.e. asterisk with PRI) can trivially set callerID to whatever they want. There are perfectly legitimate, and not so legitimate uses for this.
You don't even need the PRI. There's a number of SIP providers that will allow you to set CallerID. In some cases they do some level of verification first, but in many cases it's just a free-for-all. There were some laws passed recently which makes "faking" caller-id illegal, although I'm not sure exactly what the details are (eg, I'm fairly sure sending your cell phone number from a desk phone is fine as you own both of them).
