In the wake of all the polygon situation I was talking with some people on Twitter about this.
Even if you published a review every week or so, which is impossible, you'd still be earning a non living wage in most cities.
$300 for a review seems insane. I know it's the norm. But holy shit.
One reviewer responded when I asked how freelancers survive said "find a spouse with a real job"
Forget living wage, what about insurance? I guess in SF or New York you wouldn't need car insurance/car costs but that also means living in a super expensive city
