One can define effort in that way, and arrive at the conclusion you did, but it is not what cognitive dissonance is typically used to mean.
But that definition of effort as it relates to the ability to “survive” does not seem useful to me. It takes a lot of effort to manually dig a ditch compared to using an excavator, but you would not pay the person that shows up with a shovel more than the person that shows up with an excavator.
Edit: this is not intended to say your friend does not deserve a better pay to quality of life (QoL) ratio. However, the fact that you have a comparably favorable pay to QoL and they have an undesirable pay to QoL ratio means society does not want more people to be selling that labor, but rather more people to be selling your labor.
