I am. And it's hard to get good help when the prevailing wage for this type of work is so low. So the point was that I have no sympathy for those flipping burgers wanting 15 or 20 bucks an hour. They should try something that requires a little effort like trying to transfer a 230 pound old man from a chair or bed to a wheelchair without dropping him on the floor, or changing dirty pants because they lit him sit in one spot too long.
According to Payscale, the average wage for a nurses assistant is $11.00/hr. If the minimum wage goes to $15/hr, then that should increase as well. Maybe they'll see the pay boost matched? Then they'd get roughly $18/hr. That'd attract a more committed group of employees.
And even if the pay didn't increase to match, they'd still see a $4/hr boost in pay. That's worth something, at least.
Finally, it really doesn't matter if the employee is a burger-flipper or not, what should matter is if they are a good employee. No matter the job, a hard-working employee should be able to feed, clothe, and house at least themselves and their family without government assistance. (and get to/from work)
Personally, I think that if a company wants to pay a person so little that they'd die without help... then help should be available. But at the end of the day, that help will be billed to the company. That way, it makes more sense to simply cut out the middleman and actually pay a person enough to live on.
