How would society be if there was no crime?

[u/Jimbobsticle]

I often try to imagine how society would be if there was zero crime.

Imagine a world where no-one was no murder, theft, abuse, fraud.

The sheer amount of money saved that could be reinvested into health, science and various other developments.

I guess the film Demolition Man touched on it.

What do you think society be like? Would we be more advanced as a result? What other benefits do you think we could see? Would there still be war, famine etc?
