Oh trust me I do use that as often as possible. It seems that the next move on their part tends to be either a)to argue that we need a government imposed floor (which is simply a price control) and that bureaucrats/politicians are omnipotent in this area and know exactly what the price of labor should be and b) that no one should be "forced" to work for a substandard wage and that they have welfare, ss, unemployment etc for those people and I usually don't have the time/strength/intestinal fortitude to attack those issues as well at the same time. It's like trying to climb Mt Everest in a day
I work for an education company and we have an internal social networking site to discuss business, but off topic discussions regarding public policy do arise. I've brought up the minimum wage issue in detail, finding some vehemently opposing our views despite near total economic ignorance. I try to foster discussions from the agorist perspective to sway those people capable of critical thought, letting the lemmings show their ignorance to a company of 40k employees.
Recently, I started a thread on inflation, with some claiming public debt is not an issue, because we can just print money to pay for the debt. One person even offered that a trillion dollar coin would not be inflationary because it would not be circulated. I returned with the suggestion that, like an insanely high minimum wage, why not mint enough trillion dollar coins to cover the debt entirely, or even double it to create a surplus? The discussions tend to go dead there.
I am finding that the best way to refute a bad idea is simply to exacerbate its effects. If a little intervention is good, a lot must be great!
