You are quite right. It is most unlikely to happen because the main parties (and Reform) would rather - much rather - screw the workers and pensioners for every last penny than take anything from the tiny minority (1-5% of the population) who own almost all the nation's wealth.
God forbid that someone should be taxed just because they own more wealth than 10,000 average Joes! Let's tax the pittance paid in wages and pensions instead! Those greedy bastards on 20k a year can well afford it.
(The richest 1% of households in the UK each have fortunes of at least £3.6m, according to new official figures that show the inequality gap was yawning even before the pandemic struck.
At the other end of the scale, the poorest 10% of households have just £15,400 or less, with almost half burdened with more debts than they had in assets, according to figures released on Friday by the Office for National Statistics (ONS).) (Source, The Guardian, based on ONS data.)
