I believe you have misunderstood.
You have an employee, let's call him Bob, who is currently making minimum wage because he is new and unskilled.
You have another employee, let's call her Sally, who is making $2 more than minimum wage because she is a supervisor who has proven her worth.
When the federally mandated minimum wage is raised by $2 you now have to start paying Bob that new wage.
At this point Bob is now making the same wage as Sally despite the fact that Sally has proven herself a better employee. If you don't want Sally to walk out the door (and I assume you don't because, as previously stated, Sally is a good employee) you now have to bump Sally's wage as well.
No problem?
That is the conundrum and the reality faced by employers. Those people who have worked their way up to a living wage by doing good work and proving their worth to their employers will of course wonder why the inexperienced and far less productive newbie merits the same wages the longer termers are making.
And what the visionaries who imagine this perfect world in which everybody is entitled to a living wage whether they merit it or not--okay they just assume everybody merits it--but either way they don't consider that changing the formulas require change of other behaviors. It is NEVER as simple as significantly raising the minimum wage. It affects every single aspect of commerce and industry from utilities to infrastructure to raw materials to the finished product and it affects every single thing any of us buy in the marketplace and every aspect of our cost of living.
One would think that when there are massive layoffs that all of the lives of the people affected by that employer would benefit exponentially if giving the guys on the shop floor a few more nickels or dimes an hour.
I mean, think about it, if you lay off 10 of your 70 employees making $30,000 a year, you saved the company $300,000 in salary and about the same amount in benefits, insurance, etc.... So That is $600,000 you can now spread out to the other 60 employees. So everyone gets an instant $10,000 raise right? Somehow that never happens.
For once, I'm not saying Foxy's analysis is total BS but the situation is rarely as inelastic as she and other heartless opponents of a small increase in the minimum wage make it out to be.
