They think labour is homogeneous

"The so-called 'Fair-Pay'Act took effect yesterday and hospitality workers are expected to be the first to seek a so-called 'Fair-Pay' Agreement:

"How on earth can it be 'fair' to impose pay and conditions of thousands of different workplaces in different places with different staffing requirements ?
"How can it be 'fair' to treat staff in fine dining restaurants the same as those serving fast-food takeaways?
"How can it be 'fair' to treat businesses in big cities or tourists hotspots, where costs including land and buildings are higher, the same as businesses in small towns where costs are lower?"
