That comes out to a guaranteed $73k/year, even if you take 3 weeks of vacation. For a family where both parents are driving uber, that comes out to a family income of almost $150k/year. Considering the only skill you need is the ability to drive a car, that's insane.
They only guarantee gross pay -- that figure doesn't include Uber's cut or operating expenses[1][2]. Together, that would make your taxable income something like 60% of the figure.
