Do Libertarians idolize the good ol' days of 12-hour-work days & no labour regulations?

[Sarah]

Most libertarians believe that the free market will fix itself by people refusing to do dangerous, low paying work if they don't like the job, etc. unfortunately, libertarians forget/ignore the fact that, in many places across the country, there is no alternative. Most Americans work paycheck to paycheck. They can't just move across the country on a whim to find alternative employers that do treat their employees well. And, if there were no laws or regulations in place, employers who currently do provide better working conditions would no longer do so, making a "whim move across the country" a futile effort.
