Inflation doesn't mean an increase in the price of goods, but a depreciation of the money required to buy goods, and to compensate for this, sellers "raise" the price (demand more money per unit of goods).

By making fewer goods available to ordinary people on the same income.

Inflation affects "difficult" people in the same way. All world money is subject to inflation, which means it affects everyone, without sorting into rich and poor. The only difference is that the poor feel this effect most painfully.

Inflation is an integral part of the world economy, which cannot be eliminated in the current financial model and you can endlessly complain about it, but nothing will change. You need to accept these rules of the game and take inflation into account in your financial plans.
