A real and serious problem, and a timebomb ticking under the British establishment. The same applies in the USA, Canada and other European countries.

Such is the depth of this, the only option maybe to shut down operations at Westminster and Whitehall, form a new seat of government with a newly appointed senior civil service. Replacing the UK with a loose confederation of British states, maintaining a small federal government to handle foreign policy, defence, external border controls and a supreme court dealing with free trade and human rights issues would be one possible solution.
I'd quite like to run for Prime Minister of an independent East Anglia, my manifesto would feature a "no victim no crime" (victims could be non-human covering animal cruelty etc) legal system and a Citizen's Income instead of means tested welfare to encourage employment.
At the moment, drug dealers typically get longer sentences than child molesters, the former is no different morally to running an off licence or bookmakers. You can't help but wonder if the judges are bent in some way, there's unfortunately a culture of abuse in many of the top boarding schools they attended.
London would likely prosper more as an independent city state. Geographically smaller states tend to support a diverse population whilst retaining civic or national pride, it's difficult to operate a functional liberal democracy over a larger area.
I've started a UKAP group (UK Abolition Party) on Facebook, at present the only other member though is my other half, though the idea seems to be catching on and others have been writing into newspapers with much the same sentiments as those expounded by me.
I'm happy with different social classes, communism and similar have been tried and failed. What isn't on is different classes being treated differently in law, at present though high enough on the social and economic ladder are effectively above all forms of law. Sometimes a Tony Token millionaire is chucked in prison and usually the nicer sort of prison.
Sir Jimmy Savile OBE might one day be seen in a better light, as much a paedophile exposer as a paedophile himself. There's a saying that you can judge a man by the company he keeps, and it seems very likely indeed that there are worse offenders than him higher up the social ladder.
