Military pay checks are government issued also. They are pissed tested regularly for obvious reasons.......You got a problem with that also?
You're confusing an employer/employee relationship with a taxpayer supported service. If you choose not to become an employee, you don't have to meet any employer's demands. But with a state service, we can't choose not to participate. Taxes aren't voluntary and we're required to pay into the welfare state whether we use it or not. You can choose not to apply for welfare when eligible, but you can't choose not to pay for it. What you're advocating is the usual state strategy of taking money from us by force (in the form of taxes) and then making us jump through hoops to get it back.
I'm going to keep bringing up the health care example as long as you all keep ignoring it. Because it's very likely to be the next step in the growth of state power. When the state takes over health care, will you be as excited about a list of intrusive requirements in order to see a doctor? Will it be ok for the state to require you to prove that you don't smoke, that you eat a healthy diet, that you exercise as they tell you, as prerequisites to receiving state health care that your taxes have already paid for?
