Keep in mind that what the employer pays is about 120% of your misleadingly labeled gross wage. From my point of view the division into employer and employee contributions to what you call Social Security is quite artificial and thus think that you need to compare the net wage with what the employer actually pays.

For example, say your gross wage is 5k/month, the net wage 2.8k and the employer pays 6k. So you take home about 47% of what the employer pays.
