I don't believe it's inflation.
It's profiteering. The plan now is to charge what the market will bear.
Look at Apple. They sell less items than any of the other hardware companies. Yet they make more money. Why? Because their mark-up is far higher.
Business is underpaying workers and overcharging on products. This means that all workers are having less take home pay to buy more expensive products.
It has to do with excessive profit-taking - that's it.
