ELI5: Why aren't telephone scams stopped?

I receive the same telephone scams over and over, people using automated tough guy sounding voices pretending to ask for charity for the police, people with Indian accents and American names who say they are working for microsoft calling about my computer,  and I'm reading now that people are getting fake IRS scam calls.

How come these people aren't being caught and do we have any potentially effective means of stopping them?

Unfortunately it's because telescammers are now very mobile and use technology to both hinder people from identifying the caller and keep law enforcement from using methods to track and prosecute them.

They use techniques like spoofing unknowing peoples phone numbers, or using disposable phone numbers through less than reputable dealers that can be quickly and easily disconnected before moving to the next victim number.
