> Unemployment in Europe as a whole (including Eastern Europe) is ~20%. According to [1] unemployment in the EU-28 is actually 6.7% as of November 2018.

Everyone else is economically useless. No, that does not follow. For example, a stay-at-home spouse who takes care of the kids may be "economically useless" in a very shallow sense (i.e. they do not appear in GDP figures), but that does not make them useless.
