Do cleaners deserve higher wages? Obviously not as the market does not provide higher wages for cleaners, cleaners are paid low wages because their job requires little skill. It's the same with waitstaff, mowermen, barstaff etc, it doesn't require a high skills base so therefore the pay is low. So what will they do? Interfere in the marketplace in order to achieve higher wages. This of course will have a flow on effect of reducing the number of positions for unskilled workers. You don't need to be a genius to work out that if you artificially inflate the cost of labour you reduce the employment opportunities.
