Again, please, note that the vast majority (about 95% or more!) of the profit goes to the publisher and the vendor; only the rest goes to the developers! And that's not enough because (at least, part of) the copyright belongs to the publisher, too. So, the publisher 1) expropriates the intellectual material of the developer AND 2) rips them off by sucking away most of the actual profit. And the reason: the developers cannot make a living while they're developing the software so they need to borrow money from the publisher in the meantime, have themselves sponsored. But they pay back that money multiple times!

The same goes with most other things, even including agricultural products: traders get the money, while the farmer/manufacturers do the harder part of the job. This is how capitalism works: unfairly.
