Thank you.

I think it is important to be (at least a bit) precise in this debate.

I dislike the wording "social contribution", as these are (mandatory) insurances that benefit the insured person in case of sickness, retirement, loss of employment, etc. Discussion about the cost efficiency and fairness of the system are warranted, of course. Anyway, the current generation of retirees benefit greatly from it, so for them at least it was worth paying.

Since you are accounting all those taxes, including the VAT on the citizen's side, companies only pay the Arbeitgeberanteil (you didn't mention) and the taxes on profit?
