I think there is a mistake in your graphic. Germany does have "Employees social contributions". Or what does count into it?
We pay 18,6% (half employee, half company -> should still count completly) into the pension insurance ponzi
Then 2,6% into the unemployment insurance (half/half)
and 3,4% into the care insurance
plus 14,6% into the health insurance 

All is forced and not free to chose
