Low unemployment does not cause inflation so it can not be seen as good for the price of gold. Unemployment was very low in the late 90s, how did gold do then?
Unemployment in an of itself is not an indicator of where gold is going. I'd want to know such things as which countries are buying or dumping, political insurrections, energy prices, consumer trends...I may be wrong, but historic indicators for buying gold may be less reliable today or over the last 20 years
