I really think it's time we tried a different way of thinking about the state's money and how it is allocated.
The first step would be to stop thinking about 'taxpayers' money' and start looking at it as state money, public money, which we, as citizens of the state, authorise the government to spend on our behalf.
Put very simply, originally, 'money' was issued by a monarch or a tribal leader from their wealth. It could only be 'earned' by service to them, or, trickling down, by service to the person who'd earned it from the issuer. (it was more complex than that, but basically, the monarch/leader issued it) The money was originally minted from a precious metal, gold or silver, but eventually replaced by notes which promised to pay the holder the note's value in gold or silver from the state's resources if requested.
That's several centuries in a sentence or two but the essential point to recognise is that our money is still issued by the state. Either directly via state spending or by banks under licence from the state.
Until the early 1970s the amount of currency the state could issue had to be backed by the amount of gold and silver that it held. But when we came off the gold standard that no longer applied. The state is now able to issue as much as it wants to '*limited by* the need to avoid excessive inflation and the resources available for purchase.
Money is returned to the state by taxation. This ensures that there is not too much money in circulation to cause inflation. If the state didn't issue any money there would be no money for people to pay their taxes with. So state spending into the economy comes before taxation.
This means that we don't have to worry about raising enough through taxation to provide state services. The money will always be there.
Given that fact, we can then think of what the state spends as 'public money'. And we, the public, can chose how we want it to be spent by way of our political choices. We can chose the political party of government on its plans to spend the money it issues for the good of the state's citizens.
We need not be swayed by the 'how is it going to be paid for' question because we know that 'it' can be paid for. The state doesn't have to take it back off us because it isn't a household, it has no limit to the money it can issue. BUT, it must keep it under control and not just use it to reward its friends and relations!
If we, as citizens, decide that some of the public money is best spent in supporting the health and welfare of all its citizens 'from the cradle to the grave' then it takes away the feeling that some citizens don't deserve it because they haven't made a financial contribution to the state by way of taxation. It doesn't matter if the state spends a great deal on this care because all the money it spends goes into the economy and most of it eventually returns via taxation. In the meantime it subsidises private enterprise (because just about everything the state purchases is supplied by private enterprise) by direct spending or indirectly by state employees spending their wages.
This is not printing money ad lib. It is not going to produce runaway inflation. If the resources are there to buy, then it will make no difference, except that the economy will thrive.
