That’s not at all how prices are set in a Market as per all the applicable theories of Economics (and in practice).
Any profit-driven sellers (i.e. all except maybe a mom-and-pop shop with soft hearted owners) will charge the most that they think buyers are willing to pay, so if for example a seller becomes a local monopoly in an essential good, they’ll pump prices up because customers have no other options (with nothing on the cost side pushing it) and will act similarly when cartels are formed.
This is very much proven again and again by observeable reality - market competition goes down prices go up, completelly independently of costs.
Cost pressures will only push prices up in a market with actual competition when it affects every seller (for example if input prices go up, certain taxes go up, or there’s an event that most sellers can use as an excuse to up prices, such as widespread news of inflation in which case they informally act as a cartel would) or if the cost pressure is so large that it will bankrupt a seller that won’t raise prices (so the seller has no option than to raise prices to try and survive, even at the risk that customers will just walk away).
This theory of yours as well as the “if companies pay less taxes they’ll raise salaries” and other such Economically-ignorant theories that ignore basic market principles and causality, seem to be immenselly popular with people with certain political-faiths who have never actually run a business or worked with Markets.
Fuck economists. It is about as accurate as astrology. Except most government officials don’t take astrology seriously so it doesn’t matter as much.
I suggest you read some books about Behavioural Economics.
But yeah, most of what you see out there from Economists is really Politics, not Science.
However those observations about price making are also from Finance, and those are immensely pragmatic people (as they put real money on the line) - you might disagree with their morals (what morals, eh?!) but they certainly are putting their money where their mouth is.
Grocery prices spiked by 35% in my area over the course of three months. It wasn’t because of theft, they claimed it was because of inflation (bullshit).
Right after they jacked up the prices, theft went up. So you’ve got it backwards, actually.
You know what the geniuses in corporate office did about the increased theft? Spent $18k per store to install railing to fence the customers in.
Right after they did that, theft went up again.
Prices have fuck all to with theft, and everything to do with the idiotic decisions made by the greedy retards at the top.
