Right...The problem is always those greedy fuckers at the bottom wanting enough money to be able to live somewhere and eat. Disgraceful!
Of course not, but that's not what's being said. If people cant afford to employ them, there will be no job, which encourages things like low skilled poorly paid and often cash in hand where nothing is contributed to the pot. In things like the hospitality industry, to pay for it, drives prices up without increasing standards, so the net result is less customers, resulting in closure. It's a self creating spiral.
For an employer, it's also not just those at the bottom. How do you think the supervisor who has worked hard to better themselves reacts with more experience, workload, responsibility, when the pay gap is closed beneath them? They want and deserve more too, so costs go up to cover their increase and on it goes.
