Inflation itself is a form of taxation. It is perhaps the worst possible form, which usually bears hardest on those least able to pay. On the assumption that inflation affected everyone and everything evenly (which, we have seen, is never true), it would be tantamount to a flat sales tax of the same percentage on all commodities, with the rate as high on bread and milk as on diamonds and furs. Or it might be thought of as equivalent to a flat tax of the same percentage, without exemptions, on everyone s income. It is a tax not only on every individual’s expenditures, but on his savings account and life insurance. It is, in fact, a flat capital levy, without exemptions, in which the poor man pays as high a percentage as the rich man.
But the situation is even worse than this, because … inflation does not and cannot affect everyone evenly. Some suffer more than others. The poor are usually more heavily taxed by inflation, in percentage terms, than the rich, for they do not have the same means of protecting themselves by speculative purchases of real equities. Inflation is a kind of tax that is out of control of the tax authorities. It strikes wantonly in all directions. The rate of tax imposed by inflation is not a fixed one: it cannot be determined in advance….
Like every other tax, inflation acts to determine the individual and business policies we are all forced to follow. It discourages all prudence and thrift. It encourages squandering, gambling, reckless waste of all kinds. It often makes it more profitable to speculate than to produce. It tears apart the whole fabric of stable economic relationships. Its inexcusable injustices drive men toward desperate remedies. It plants the seeds of fascism and communism. It leads men to demand totalitarian controls. It ends invariably in bitter disillusion and collapse.
