I can't answer for Newman. For myself, I'll say no, of course not. Each party has the amount of power dictated by supply and demand. Employee negotiating power varies directly with some factor of the employer's demand for the employee's services and inversely with some factor of the supply of those services, give or take a constant. The opposite is true for the employer. I still don't think this affects the question of whether a voluntary transaction violates any rights.
Trad basically answered how I would but I'll still throw in a couple things...
It is true that in some situations the employee actually has the upper hand. If they have high level skills in a job market that has a small supply the employer will be in the weaker position and may end up paying more than they want to get that worker. In other cases the situation is flipped.
I would venture that the majority of cases where the employee has the upper hand are for jobs where the minimum wage is never an issue because they are skilled jobs where the wage is going to be high. It is the low level jobs that the employee has the power on and that is where the minimum wage comes in.
How voluntary is the agreement when the job applicant is desperate for a job and the employer isn't desperate for the position and/or they know there are lots of other workers out there who can take the job if this person won't?
The argument is often brought up that if the wage is too low they can simply keep searching for a job that pays a higher wage but things aren't always that cut and dry.
My post about unions was partially sarcastic but I do think there is something to it. Employees joining together can help with power disparities between the employer and employees.
Of course, employees are not all saints so the employer can end up being taken advantage of in some cases.
Perhaps the best position is a middle ground where there is a minimum wage but it isn't a blanketed across all jobs. It is based on the industry, company, region, etc. Similar to what Buzzword suggested.
