Oh, indeed, I want to see as many businesses as possible adopt this $15/hour or $70000/year concept. Why? Because if I tried to explain how economically and socially stupid this is, you would simply reject what I have to say and call me a heartless bastard. So, what has to happen is we adopt this and, when it fails miserably 10 years from now, you'll understand. All we will have done is raise the bar for the "poverty" level and lower the incentive to become more skilled.
Why even stop there? Give everyone a new house, nice car, iPhone, etc., just for being born. You want it, you got it. Isn't that where this is headed anyway: not equality of opportunity, but equality of outcome. Minimum wage was intended only to get skills and experience on the path to getting a better job. If too many people today are trying to support a family, own a car, pay for an apartment solely on minimum wage, that's not a problem with the wage - that's a problem with them trying to do too much with too few job skills. I have been there and skimped by with nothing until I could get a better job.
One thing I'll agree to is that we need to bring back trade schools. Another thing that would help is if our politicians actually had owned and operated a successful small or medium sized business.
Already, a woman is complaining that at $15/hour, at Walmart, she can't support her four kids, make car payments, and rent. The path to improvement for her really isn't high minimum wages for everybody, because she'll eventually be back in the same situation. She needs the opportunity to get more skills for a better job.
Also, if a business is going to need to hire someone to sweep the floors and clean, and they have to pay at $15/hr for this, they're not going to hire the zero-experience 16 year-old who isn't likely to stay past summer vacation - they'll hire a more experienced person who has the potential to take on more responsibilities and will stay longer. Or - more likely - they'll hire nobody and just spread that task out among the current staff. So, the youngest, least experienced lose out.
All who like this "living wage" concept should adopt it and live long enough to suffer the consequences.
