That’s just wrong on so many levels. If I look at just one error, inflation doesn’t affect everyone it is a tax on savers ie the rich. Wages and prices go up with inflation (prices by definition), but cash and savings go down in real terms.
but "tax on savers ie the rich"
rich normally are rich enough to protect their savings from inflation. e.g. by putting it in an effective monopoly - land or housing (housing is a monopoly if you also are rich enough to have some influence on what / where houses are built / not built)
People with money pretty readily deploy that money into investments that beat inflation.
