The three points

1. software is easy to write
2. in a business, the software is the icing on the cake
3. software developers are cogs in a machine, or interchangeable components of an assembly line

These are pervasive within business. There's a strong divide between business folk and workers. To business folk, they are the major part of the business. Without them, the business would not exist, therefore they deserve the higher salaries, the big cars, the nice yachts, the position, the power, the wealth. Workers of any kind would be mindless drones that implement and execute business dictations, therefore they may be replaced at will, and pay vs worker happiness can be min-maxxed.

If we want to change that dynamic, these kinds of people ("hey bro, I have this idea you can implement for me for free") should not be allowed to become business owners. Worker-owned collectives should be the future.
