Because that’s not how it works, neither in the scale of the store or the more macro scale of society.
A burger flipper makes more for McDonalds than he is paid, so right off, he is contributing more value to his employer than he is receiving and that alone is enough to completely invalidate your assertion.
Second off, if you want to have Mcdonalds cheesburgers, then someone has to flip them. If no one can flip them while affording to live off the pay offered, then no one can flip burgers.
Maybe you do not consider McDonalds to be a contribution to society, but that is the case for any low paying job. If it doesn’t pay enough to live on, then it just isn’t going to get done.
We allow employers to have access to a pool of workers willing to work for cheap, to ask employers to actually pay enough of what they make off of them so that that employee is capable of living a basic lifestyle is not offering them more than they contribute.
If you are not willing to do the job at the pay that they receive, then they are contributing more to society than they are being paid.
Just because there is less demand for lower skilled jobs than there are people who need a job, and so they can pay less, does not mean that they are not necessary and useful to society, it just means that we can exploit them for less than they are worth. Then, those who believe that someone’s worth is tied to their paycheck, can see that they don’t make much, and so therefore, aren’t worth as much as they are paid. It’s an ugly, circular logic, but it’s a great way to justify treating those who are less fortunate as though they deserve their misfortune.
Having low paid workers gives the consumer cheap goods and services, and gives the employer profit off of their labor. You can clearly see that a low wage worker contributes far more to society than another six figure paper pusher whose pay comes from the profit off the burger flipper’s labor.
Then third, what a person contributes is also tied to what they spend. If Someone has $10 in their pocket to spend, then that is what they contribute to the economy. If they have $20, then that is what is contributed. From a logical, macroeconomic perspective, they are always contributing exactly what they earn.
Sorry, we are discussing left wing dog whistles in this thread. What are you doing bringing up right wing dog whistles?
