Here is a short post on the dangers of hiring only people who are employed:
It’s worth highlighting how important that social contract of taking care of others who are down whether it’s because of circumstance or bad choices. Without an implied and explicit agreement about how to treat each other fairly, respectfully, and compassionately, society is likely to become less effective in whatever it does. Competition is no fun without a spirit of fairness. A marketplace is useless without a healthy, vibrant community that supports it.
I wonder if this is why universal healthcare is so challenging for the United States to grasp. It is an example of a social contract that essentially says, “I’m going to take care of you when you can’t knowing that it may happen to me as well” (see The Truth About Canadian Healthcare). There are plenty of disagreements in trying to build these contracts (as will happen when people get together to do something), but at least there is an underlying belief that we do rely on each other. No human being stands alone even if they delude themselves into thinking it.
