What's a fair salary? Pretty much all answers I've heard to this question will have to define the salary in relation to myriad cost inputs (housing, healthcare, transportation, food). The fact that the answer to this question is almost universally defined in terms of cost of life necessities means that the current salary could be fair if the cost inputs were cheaper. It also means that any salary that would be fair given current costs would suddenly become unfair again if the cost of those inputs grew proportionately (inflation). This suggests to me that we're better off focusing not on policies that raise salary but instead putting our efforts towards lowering the costs of only those cost inputs we deem as necessary inputs for living circumstances that are considered fair. Solving the cost of only basic necessities once permanently solves the fairness problem. Trying to solve the fairness problem by raising wages with no policies to protect against inflation of basic necessities means that you will only ever solve the fairness problem temporarily.
