I think you got this wrong. Laws against Scheinselbständigkeit are protecting individuals from being exploited, and it's one of the things that characterizes the EU.

Don't forget that outside of Europe, most big economies were built on the ongoing exploitation of the working class. I am not saying this didn't happen in Europe, but at least there are efforts to curb this.

So a CIO complaining that he can't exploit people for cheap labour is not an argument for broken IT laws. It's an argument for seeing that it works as intended.
