6% unemployment is a pretty normal rate for an economy. Historically the US is usually above 5% [1], and the current rate is 4.2%, so 6% is only slightly above the national rate.
I don't doubt that you've had trouble finding work, but I don't think the unemployment rate is the reason, or even the symptom. Particularly since it sounds like you are looking for remote only, and the ratio of seekers to jobs (a sort of "unemployment" measure, given that people may settle for in-office jobs if they can't find a remote one) for remote software may be very different than a 6% rate.
