I think we're going to see a major re-alignment of parties and party loyalties over the next few years. I don't have a crystal ball, so I don't know how it will work out. There is a chasm in the centre ground. I suspect most people want the same things - somewhere reasonable to live, fair rewards for working, feeling safe when they walk around, schools and a health service fit for purpose, etc.
Like you, I feel a mixed economy works best. Markets usually find the right level, but when they fail (as they are in housing) the government must step in to rebalance the situation. I believe it's obscene that individuals are making vast profits from health and education, which should be a basic right in a first world economy. I would, for example, love to see a national audit of education spending and see how much is being spent on consultancy, outsourcing of functions such as payroll and HR, CEO's salaries. This is all money which could pay for smaller classes and teaching equipment.
I would also like to know how much in total is being spent on G4S, Serco, Capita and the various work programme providers and to compare what they provide with 10 or 15 years ago. I don't believe for one moment that the mantra 'private is best' is true.
I feel that we're trapped between two ideologies. Personally, I prefer pragmatic solutions. If there's a problem, it needs sorting. Societies need to provide red lines, but if the solution involves bringing in private providers or adapting public services and/or the law, that's fine. I would like to see every citizen having a basic understanding of macro economics, so that they understand that a national budget is not like a household one.
