Try this: Allow firms to inflate up to 2% per annum and if they either don’t over inflate (over 2% per annum) or reasonably deflate their prices they receive a 1% gift of net profit. Then index the retail discount/rebate to the monthly rate of inflation, so 3% monthly inflation and the retail discount/rebate becomes 53%.

Any larger increase in prices receives no gift of net profit, gets taxed at a very high/up to 100% rate, and the combination of a $1000/mo. universal dividend, huge increase in purchasing power with the retail 50%+ discount and additional demand due to decreased payroll taxation for welfare and unemployment insurance insures plenty of demand even in extreme circumstances.

All for unionism, but the 50%+ retail discount policy which is a 100% increase in purchasing power enables the union to focus on other means of commercial malfesance

Blatant and even moderate Greedflation is taxed at a rate of at least 100%.
