Libertarians

Do you want to repeal the child labor laws, the 40 hour work week and the minimum wage?

But are you really free in such a society?

Let's assume you work 40 hours a week for $50k a year. Along comes someone with similar ability who will work 45 hours a week for $40k. Either you drop your price, or work more, or get replaced. Now consider that happening repeatedly across the entire market.

After a while you end up with many people working unhealthy hours for little wage, since there is always someone desperate prepared to replace them. You could decline, but then you'd have nothing to eat. Is that freedom?
