No doubt some of these ideas will be controversial or even offensive to some/many, but looking at things objectively the current system is so broken and offensive itself that I don't think we could sink much lower no matter what we do.
I'd bring back hanging, not just for the most serious crimes but for low-level repeat offenders. This would save a fortune in the long run in terms of the cost of running prisons and the justice system. There would be no right of appeal, a straightforward process of execution shortly after conviction.
I'd freeze prices at their 2019 levels to end inflation. Whatever something cost in 2019, that's what it costs going forward.
I'd ban anyone worth more than 500K from holding political office or being in a senior position in a company or other organisation.
I'd change the tax system so that anything over 50K per year is taxed at 99%.
I'd do what I originally typed this paragraph but then deleted because objectively speaking it's probably too offensive to be posted here.
Over time, I'd reduce the cap no longer explained in the preceding paragraph by a million or so every year.
I'd legalise the personal ownership of firearms. This would raise a fortune in taxation because hardly anyone who wants one is allowed to have one at the moment. This could be a real growth industry because as more people bought them, others would feel the need to buy them for their own protection. At the beginning I'd limit ownership to those over 25, to see how things went.
I'd introduce a national community service scheme for young people. They'd be forced to work in community schemes for a few years and could not be released until they've performed satisfactorily for a set period of time.
Trade unions and strikes would be banned, to be replaced by a guaranteed minimum income of 20K per year, with a guaranteed 5% payrise every year. Company owners would not be allowed to make staff redundant, if they do they face imprisonment (if it's their first offence, or execution for repeat offenders).
I'd scrap the TV Licence.
