To which standard can you point out to someone and tell he is exploited ?
Who judges what the asymmetry is ?
On what standard the bureaucrats of Washington can judge that the trade between two persons he does not know is asymmetrical, and thus coercion on the strong one should be used to be fair ?
Don't you think that in such system, the bureaucrats will eventually get bribed ?
If an employer is prevented by law to fire his employee, and his employee is not doing his job and profit his position, who is exploited, who lost his free will ? (it is what happen in France)
And then you wonder why enterprise are so fearful to employ someone and on the defensive.
I don't care since I profit from it with my higher rates as fire able consultant, but I am much more secure and free than any employee can be, and always dealt equal to equal with my customers on my free will.
For labor laws, you guessed it right, I am for voluntary child labor, where the child can decide if he works, where he works, and for how much and trade himself for it.
It will solve the dilemma of school being out of touch with economic needs. (Economic need is nothing but the need of society)
The condition of schools today are way worse than work.
As you may already know, legal framework is always in flux and should reflect the needs of society at the present time. Regulations are added or subtracted as needed.
What you are proposing is currently illegal for under 14 in US. I would protest that type of deregulation for reasons of consent. I dont think minors have ability to consent to matters they have no experience in and it would increase their. chance for exploitation. And also I believe that society thrives on education. If suddenly a large population of children chose work over school we cannot remain competitive in future generations
