B,
5 years ago I did read a 1st-Year undergraduate Economics textbook, cover-to-cover.
However Economics/Public-Finances is not my area of expertise; I make no pretence to being knowledgable on the subject, and I know that I don't know enough to make any practical suggestions.
A Host of Posters on this and other Threads have stated that *they* know that the UK Government is currently doing Things wrong, but I don't see any suggestions (here) about what could be done to improve the situation.
I would like the UK Government to be able to balance-the-Books, but currently (it seems that) the Government just doesn't have enough money available to keep a-large-fraction-of-The-Public even remotely "pleased" with current Public-Spending decisions. -- Rachel Reeves, as Chancellor, is in a *really* tight bind.
