"Theft" is a solvable problem that many people don't think about.

Theft is just a function of poverty. It's that simple.

Nobody (except mentally ill kleptomania maybe) in good payed white collar parts of society goes out pickpocketing or robbing houses at night. That's all the proof you need.

With the speed at which humanity is becoming richer crime has fallen a lot even since the 90s let alone the 1800s or in the future... Theft as a concept will be literally solved
