What I tried to say (and perhaps didn't) was scientists won't necessarily be good for a country, not that they'd be bad.

The german minister of justice, Sabine Leutheusser-Schnarrenberger, did a lot of good for the german internet. Her decisions were very rational and fact-based, yet she holds a law degree.

There just are too many good politicians without science degrees for the sweeping generalisation "scientists are good and lawyers bad".
