The only situation I can image in which there would be no scammers, would be if everybody on earth had whatever they want. If there was no poverty and everybody had an abundance, then there would be no reason to steal. This doesn't seem likely to happen anytime soon, so there will probably continue to be scammers. All we can do it try to protect ourselves from scams and fight to catch scammers in society. It seems like a lot of scamming happens by phone in the US. As far as I understand, it is incredibly difficult to trace phone calls and they are usually made from other countries. Something needs to be done to make it easier to trace these calls and charge the scammers for what they are doing. I think email services like Gmail are doing a great job at minimizing the amount of scam and phishing emails that get into your inbox.
