I get the concept. But realistically that would mean three things:
In a region where people make 250k a year for them to live paycheck to paycheck the cost of living would need to be somewhere around 4-5x higher than in an area where people would make 50k a year.
That would further mean that in the areas where people make 250k a year noone would exist that could afford anything less than that. So the grocery store cashier and the gas station clerk and the postman would all need to make the same money as google software engineers. That is clearly not the case.
And thirdly that means that either the people who make that much money living paycheck to paycheck are economically illiterate and dont grasp such simple concepts... Or which is far more likely, the quality of life in high cost of living areas is in fact so much better, that it is worth paying the extra.
Either way someone who can make 250k a year is choosing to life paycheck to paycheck by choosing to pay such expenses. They definetely have the means to work somewhere where the difference between cost of living and paycheck allows for saving signficant amounts of money over time. Claiming those people would be victims of the system who were forced to live paycheck to paycheck is simply not true. It is still very much their own choice.
So where is that place, where the cost of living fully eat up a 250k salary, or even a 100k salary? And by eating up i mean actually living paycheck to paycheck, not as given in the examples enjoying many small luxuries that add up, but are not realised as such.
