Must say I agree with most of Chip's points to be honest. Wouldn't do things too much differently myself.
And I also agree with Lee, that you should have to have a licence to have children. Having a child you can't afford shouldn't entitle you to claim loads of money from the state, you should work for it.
I'd also scrap a lot of university places and put emphasis back into the further education system, with apprenticeships and try and get some value into some honest graft. We shouldn't need thousands of migrants doing vocational jobs, we should be training our own young people to do them, rather than telling them all to go to university and get a degree in computer games design, drama, psychology or the other faddy subjects. Course places should be capped unless the qualification would be in a useful subject, so universities produce teachers, nurses, doctors and engineers, not a load of people who have a useless degree in a pointless subject area.
Also, scrap road tax altogether as it serves no purpose. Road users should be taxed based on mileage, so just have road tax as part of the fuel duty system, so the more fuel you burn, the more you pay. And the proceed go on maintaining and improving the road network, as well as making public transport better, which may encourage people to use it more.
