I don't choose parties which go for low taxation, Jane. I would go for a party which went for fair taxation.
But taxation doesn't fund spending; spending has to come before taxation else there's no money to tax.
We spent our way out of austerity (or would 'depression' be a better way to describe it?) in the 1930s and most notably after WW2. Yes, the money post WW2 came from the USA but the point is, whatever the source, we spent it and the economy responded. Massive housebuilding programme for a start, with a boom for all the related industries and businesses. It was the foreign debt and having to stick to the gold standard which ultimately caused problems, as well as failure to modernise.
Ironically, the panacea for lifting communities out of poverty is usually held to be investment. If it works for a deprived community why is it frowned on for a country?
As far as I can see, all that austerity has done is increase welfare spending (causing the government to respond by cutting benefits to make the money stretch) and cause people to have to take low wage and insecure jobs in an effort to survive. Not only that, but it has led to damaging cuts in public services which are affecting people's health, safety and wellbeing (I'm thinking of things like libraries and the arts here which contribute to our enjoyment of life and so our mental health)
I could go on but I don't want to bore people any further...
