Say we increase the wages of some. The cost of their product, may need to go up, to maintain the business bottom line. This then makes the buying power, of all consumers, go down, giving everyone an affective wage decrease. To make ends meets, others will ask for a wage increase, to offset the extra costs, due to the wage increase of the first group, whose product they need to buy. This increases the costs of the new goods, and takes away the wage increase of the first group, and sort of gives it back to the second group. Everyone has more money, on paper, but we now all have same buying power, as when we started. It is sort of smoke and mirrors.
How could someone get by with $1.60/hour in 1970? Adjusted for inflation and cost of living, that small amount went 40% further back then.
Wage increase without increase in productivity or better economies of scale; cheaper raw materials or more automation, becomes a zero sum game, where some will win in the short term, while all pay the price, until all win and all pay, for a wash; cost of living increases. Wage numbers mean less than buying power.
The average price of a new car in 1970, was about $3500. In 2023 the average price is about $43,000. The price of cars has gone up about 12X. If we multiply $1.60 X 12 = $19/hour car buying power for 1970's minimum wage.
An experiment is being done in California, where fast food workers are now required to be paid a minimum wage of $20/hour. It will interesting to see what happens, but it is predictable. It is likely, the price of fast food in California will go up, increasing the cost to the consumers. Unlike big government, businesses cannot operate in the red for very long before collection agencies visit them.
Some consumers will now have to cut back on their fast or food, or go elsewhere where food is cheaper. Since the demand will go down, the fast food restaurants may need to lay off employees, which means a pay cut, for some, back to $0/hour. The employees who are left, will now may need to work harder and become more productive, to make up for the daily work load, with fewer employees. This will make their $20/hour make more economic sense; worth that wage. Since we now back in balance, will prices come down? Maybe not. The prices may stay higher to make up for the initial lost revenue; too many employees at $20/hour, and to see if consumers will get use to the new price structure; cost of living increases for all. We all may have to ask for a cost of living increase from the boss, who then has to raise price, again.
