Who is the "we" here? Because the profit margin not being high enough is certainly not a problem for consumers. The only people who should care about that are the company's shareholders and "shareholders" certainly isn't synonymous with "society".
But the point is locking up money in a 3% margin business doesn’t impress investors.
So you either need to improve the margin with lower costs or higher price (or both). Or bail from the market entirely and put your money in something that makes more money.
I think people often forget that in a society we rely on companies making and serving things. They make our food and our medicine and build our homes and make our games. It's a good thing when their finances are healthy. It's a bad thing when they form monopolies and rent-seek.
This is madness and it doesn't make any sense besides the one case where you pursue a monopoly.
All of this has nothing to do with the consumer of the product besides the fact that he'll get a worse and worse product while simultaneously being forced to pay more and more. Enshitification is aresult of this "healthy" business culture.
Many of those developers may not have the job elsewhere, or job paying much less. They now have the experience working in a proper software engineering environment.
