That's a good point, but I'm a bit more contrasted about hourly rates. It's typically (at least for me and what I observe) increasingly hard to maintain a high hourly rate while making more hours, since it implies getting less and less selective with available paying tasks (or having an overwhelming demand, but in which case, one should increase her hourly rate anyway). In my case, it'd be borderline impossible to transform to just transform 2 hours of leisure/free time into paid work at my standard hourly rate ! (but of course, my life isn't organized for this to begin with).
