To Clarify My Point Simply:
People will have about $1000/mo in rent, $500/mo for food, $500/mo utilities/phone/internet, $500 car/insurance, $500/mo health insurance, $300/mo debt services, $300/mo other expenses. That's $3600 or $22.5/hr NET pay. Now some of these numbers might be considered high, but they're pretty close to accurate overall. Even if it dropped to $3000/mo, we're at $18.75 NET. So that's where I come up with $20/hr+. It covers a place to live, food on the table, a decent car/insurance, health insurance, paying off past debts/funding retirement/savings, and some other expenses.
The math is simple. $20/hr is a true living wage and that's why people want/expect it from a full time gig, especially for skilled labor.
Now I completely understand why people will balk at these numbers. I feel the small business squeeze just like everyone else. I can't follow these rules. I hired a college educated about 18 months ago at below $15/hr because that's what I could afford. My point is simply that if you want to find a good employee, who has a good head on their shoulders, and doesn't come with a ton of baggage, $20/hr is that magical number at the moment.
