I used the term “extreme left”, “hard left” of you prefer do they support MMT? I have no idea, what l am pretty sure of is that they would borrow/create a large amount for social improvement. Investors are not at all interested in the comfort of the population, they want to see a steady growth of the economy, if they can’t see that the currency value will fall.
Problem is, at the moment, Katie59, that there is a great reluctance among possible 'investors' to invest in the UK. By 'investors', I don't mean those who speculate in the financial markets for the sole purpose of increasing their wealth through the buying and selling of shares and gilts, or by shorting, or any other financial device that will increase their wealth, I mean people who are prepared to invest in businesses in the UK. And the reason that they are not prepared to invest in UK businesses is that they see no prospect of businesses making a sufficient profit because they don't see potential consumers of their goods and services having enough spare cash to buy them.
Wages are failing to increase in real terms, inflation is eating spare cash and savings which are being used to purchase the very basics of life, such as fuel and food, and the increases in interest rates are further reducing the amount of spare cash available by increasing loan repayments.
The only prospect of improving the economy would be from state investment, improved spending on infrastructure, on the NHS (which is a very significant contributor to GDP) and on public sector wages, would stimulate growth by making more money available to be spent in the private sector.
As I persistently point out, the money for state investment doesn't have to be borrowed, nor does it come from taxation because taxation doesn't fund spending.
We know that it doesn't have to be borrowed because we have had some £900 billion of QE money 'created' over the past 14 years. With absolutely no adverse effect on the value of the currency. Heavens, the injection of QE money just after the Brexit vote supported the value of the pound, which dropped like a stone on the announcement of the result.
The key to promoting growth would be targeting the state investment to where it would produce the most economic activity. It needs to go to the part of the population, and state enterprises , where it is most likely to be spent into the economy, not to the already wealthy (as Tusses proposed tax cuts for the wealthy) because they don't spend extra money into the economy. Trickle Down is a completely debunked idea.
Of course, this is a simplification but the underlying principle is that investment should go where it stimulates economic activity.
