They aren't hiring because it wouldn't be profitable to the businesses despite helping out the unemployed.
Are you insinuating that the primary role of starting/running/expanding a business is to create jobs?
We may not want to acknowledge it, but the primary instigator of starting/running/expanding a business is to create a profit. Certainly, an ancillary benefit to the s/r/e is providing jobs and, (if it applies, and by extension) helping the unemployed.
But the notion that it is altruism as a motivator that prods someone to undertake the considerable risk and liability that ensues with the launch of a private venture is simply untrue in the majority of cases.
Capitalism can offer numerous benefits, but not if emotionalism supercedes business decisions.
