Both cases are possible. Wages may be low because of surplus of working force on the market (hence no incentives to rise wages) or can be result of extremely low margins at the given industry.
There can be tens of reasons why wages are poor, and rising minimum pay solves the issue only in some cases
Of course, there will be edge cases of industries that have not improved their margins over the years. But the fact that prices follow inflation, and wages do not, is enough information to generalise that businesses are just greedy as fuck.
