Re: Howabout..
Easy way - legalise all drugs and tax them. (Keep the quality high and at a price that cannot be matched by the criminals.) Overnight it would turn into a much smaller problem (Like we have with fake and cheap alcohol / cigs being sold in council estates.) People being able to grow hemp to make paper (Faster and Cheaper than using what they use now) might upset the status quo but it needs to be upset and the solution needs to be radical. (Cuts won't work not done in the way they are trying now anyway.)
A solution that works (Because it will involve making a fairly big change) will never be popular with the Daily Mail reading types.
The problem we have is the baby boomers basically who were given everything by their parents generation (Who also took part in a war from them and had a really hard time) have left nothing for their children and took everything for themselves. I was in a pub on Christmas Eve with a fair few people of my dad's generation I was close to punching a few of them. (They retired at 50 on really good pensions that cannot ever be reduced). I think each generation should have it better and easier than the last due to enhancements in Technology / Medical stuff.
What we should be doing is trying to reduce the amount people have to work to 4 days.
(My grandfather's generation used to work 4 1/2). Instead of just creaming off the profits to pay for the people who went to school and university with Cameron. (Clegg is worse though because it outright betrayed everyone who voted for him).
People working for the Public Sector did so on the grounds that they would make less whilst they were working in return for a good pension. (My mother when she left university had 4 friends with the same results as her - 1st Pure Maths - She went into teaching because she wanted to do it but she could have been an acturer / finance director of big PLC's / Professor of Maths - screwing people over at the end of their lives is not a good thing to do.)
I know a retired fireman (Over 70) gets an absolutely insane pension keeps going up. Same as police they retire early if they want to (With a full pension) and then get another job. No reason they couldn't do a desk bound job. (At the moment they just get another job.) That is nothing like teachers.
It is going to get to the point where especially in London the only teachers are immigrants as they are the only people who could and are willing to work for what is on offer.
The only way to improve is to invest in the young. It is only going to get worse if really expensive private schools are the only places with good teachers it won't work.
Maybe we get a meteor hitting the earth or another ice age starting that changes things when people realise how pointless things are these days.
(My parents will get a huge cash injection also when their parents die (They were born during the war and had nothing and lived in council estates and worked very hard and ended life pretty rich) for people starting now with nothing something like that just isn't possible. If your family is very poor now it is far more likely to stay so no matter what they do which is bad.
