That’s more of a function of corporate greed than anything else. They’re all hiding behind each other while ripping you off, and getting away with it because it’s difficult to call out any one company when they’re all doing it.
What are you going to do about it, compete in the marketplace? The barriers to entry are high enough that that is extraordinarily difficult. And if you do manage it, why would you charge less than market rate? And you’re likely to just get bought out by a bigger competitor anyway, so grats on your cash out.
