I dont believe that at all. one should not be paid 20 buck an hour to pick apples, or take an order at mcdonalds, the job is not worth that much, if it were our food would cost double and we would be in the same boat. just because you now make 50 grand instead of 25 sounds good, but if the cost of everything goes up to match that change, whats the point??
Well, for starters, if a McDonald's employee needs food stamps to live, then I'm subsidising McDonald's from my taxes: I'm paying part of the income of their employees. Same goes for apple-pickers, and every other job for that matter.
Allowing a company to pay a lower than living wage results in a massive market failure, and consequently waste of resources. It's much better to force McDonald's and your local apple farm to charge the customers the price of resources - including human resources - it actually takes to deliver their product, and let market decide if it's worth them. An employee must be able to live on his wage alone with a tolerable quality of life, otherwise the employer is simply a parasite upon the economy.
