If you make sure that your government employees are educated, provided with good benefits, feel like they have an impact, etc., the outcomes will invariably be for the better.
A very good example of this is teachers. The OECD tells us:
"[...]in nearly all countries, when teachers perceive that appraisal and feedback lead to changes in their teaching practice, they also report greater job satisfaction. When teachers believe that appraisal and feedback is performed only for administrative purposes they report less job satisfaction. In addition, teachers who report that they participate in decision making at school also report greater job satisfaction. Indeed, although fewer than a third of teachers believe that teaching is a valued profession in their country, those teachers who report that they can contribute to school decisions are more likely to report that teaching is valued in their society."

And other sources tell us that satisfied teachers tend to lead to better outcomes.

In other words, much like regular companies, governments with happier employees tend to have better outcomes. This should be hardly surprising to most HN readers.
