I don't think MMT is relevant Maisie.
Well, I do, DAR, because if you can understand what MMT tells you, which is how money is issued by a government into the economy and that it is description of how money issuance actually works, then you can ignore the 'how are you going to fund it?' question which kills parties at General Election time if they don't conform to the 'taxation funds spending' myth, you can make better judgements of parties' spending plans. Asking, who are these plans going to benefit? and, are they plans which will benefit the whole economy and the people within it?
This is an unknown, untried form of Economics. It is currently only backed by a small minority of economists. I can't see why you would think a political party would put it forward at this point in time.
It's not aa 'form of economics', it's a description of what happens. As I have said, countries have done this for years and years. I note that no-one is responding with any different theory of how the supply of money in the country has expanded along with the growing population...
Political parties don't dare put anything except the taxation funds spending myth forward because voters believe it, compare the national economy with their own household economy, and vote accordingly. Not on the actual policies but on their perceived cost.
The large amounts of money raised, as I described, by QE and for covid are examples of government money creation in action. The government bonds, to the tune, by now, of some £800 billion, which were 'purchased' by the Bank of England, on the instructions of the government, were purchased with money created by the BoE for that purpose. As the BoE belongs to the state and the state can't owe itself money any pretence that it is costing us anything is nonsense. The interest that the BoE pays to itself (the nominal holder of the bonds) on behalf of the Treasury (i.e the govt.) is an accounting fiction.
I agree with your analysis that voters are hoodwinked by political parties, but if they know that they're being hoodwinked they are in a better position to judge the value to them, and the country, of the policies which parties propose.
I reiterate that the essence of MMT is that it is descriptive. The reason that many think it is also prescriptive of left wing ideas is that most of its proponents tend to be left wing. But, as we saw with the covid money, the right wing is just as able to use it to further their own policies, channelling created money to mostly enrich their supporters and donors.
