Well the Conservatives have made a good start by simply legalising crime, the Brexit Referendum swindle they got away with being a cardinal example.
That's the easiest way to eliminate crime, pretend it never happened.
They have already made that crime legal by default, all they have to do is to widen the scope of that policy
Terry Pratchett foresaw an answer to the problem in his Discworld Novels
He envisaged Crime being organised into Guilds
"
The Patrician
Lord Vetinari made the guilds register with the
Patrician's Palace, and made them regulate their members' behaviors. For example, before the legalization of the guilds, thieves could rob and mug as many people for as many times as they, the thieves, liked, and the monetary gain may be high or low depending on luck or hard work; after legalization, the
Thieves' Guild makes money mainly by having rich people pay an annual premium so that members of the guild do not have to break into people's houses and rob them. This and similar systems make life more predictable, and people, including the Thieves, have time to get on with their lives.
Guild enforcers police the behaviors of guild members and make working a privilege of guild members. This ensures two things: clients will get fully professional services, and guild members can charge a high price for their work. Guild enforcers have the right and indeed duty to catch and punish a working non-member; this kicks the
City Watch out of a lot of its traditional jurisdiction (A cop will only catch you. What would, say, an Assassin do to a freelancer?). A Guildhouse and its grounds are considered private properties, and even in case of a suspected crime are not to be intruded by Watchmen. Many guilds take in orphans and train them up in guild schools, giving them skills for a career for life- the surnames (
Clockson,
Ludd) are a telling sign of this heritage. Some guilds, such as the
Assassins' Guild, offer such a high-quality education that people pay for their children to be educated there. Many guilds hire their own physicians and run their own private hospitals for members.
Somehow it makes me think of the notion of Having Private Health insurance instead of the NHS, carried to it's logical conclusion
