Education - we need a massive increase in non academic options, both at school and in further education, plus a massive increase in adult education, i.e. GCSE and A levels at evening classes, funding for college courses for plastering, plumbing, electricians, mechanics, etc., plus HGV/PSV driver training and tests. Basically encourage people, young and middle aged, to get better qualifications, skills, trades, etc. We've had far too much emphasis on Unis for 18 years to the detriment of other options/other ages, etc.
Taxes - complete reform and simplification, scrap NIC and increase income tax instead, smooth the cliff edges, ban any marginal tax rate over 50%, take a hatchet job on lots of allowances/reliefs that are manipulated, massive recruitment for tax inspectors so that there are the personnel to tackle the black economy, VAT fraud, "back pocket" traders, etc.
Policing - massive increase in numbers of police officers on the streets, do whatever it takes to reduce paperwork, set up country wide/regional depts to tackle things like money laundering, drug dealing, people trafficing, scams/frauds which aren't restricted to "local" areas. So basically get back to "local" policing for local matters such as anti social behaviour, traffic offences, burglaries, etc., but national policing for national "cross-border" issues.
NHS - again, massive restructuring needed, from the ground up, scrap GP surgeries as the "gatekeeper role" and create a network of small "clinics" for treatment of minor injuries, and basic prescriptions, - like in many countries in mainland Europe. More "self referral" for things like hearing aids so you can go direct like you can with opticians/dentists, etc. More smaller hospitals, i.e. back to one in every town, instead of these "super" hospitals that can be an hour away even in towns and small cities. We shouldn't need to travel from one county to another just to get a broken bone x-rayed! Sort out the dire communication problems where one consultant can't see the x-rays, blood test results, scan images etc that another consultant/doctor has done!
Localism - I'd like to see a reversal of the "centralisation" over the past few decades and incentives for shops, employers, organisations to move back into local areas. For retail, that's more local shops in villages, precincts, etc rather than the High Street or out of town retail park. For offices, that means more regional area offices, more satellite offices in smaller cities and towns. I'd love to reverse Gordon Brown's crazy idea of closing all the small tax offices and centralising tax advice/processing into a tiny number of huge "call centre" type offices. Basically stop the centralisation of everything into London and other big cities and get back to decent jobs being available for people in smaller cities and towns to stop the "flight" of local people leaving to go to Uni and never coming back to their home town due to lack of decent jobs!
