Yes, why should that be prohibited? The only rationale I can think of would be to protect people from themselves, which I do not believe to be a proper role of government.
Does indentured servanthood seem like a radical concept to you? It doesn't to me. It is how a lot of our forefathes escaped a sure fate of poverty in England and were able to come to America, learn a trade, and eventually be able to buy land and better themselves. It is a lot like joining the military. You give up your freedom for a term of years in exchange for an opportunity that you would not otherwise have. Why in the world should people be forcibly prevented from entering this type of arrangement?
Unfortunately the cost of indentured servants exceeded the cost of procuring slaves, so many employers switched to slavery in the late eighteenth century. By the time indentured servitude was outlawed, it was a mostly dead practice, replaced with slavery, an entirely undefendable practice.
But it does show the caliber of people who engaged in hiring indentured servants, the same kind of sleezebags who had no moral qualms with keeping slaves.
This sort of man, the sort who have no respect for their fellow man's rights, are good for one thing--using force against to stop them. They are animals, and animals understand only two things: hunger and fear.
I don't think today's crop of big anti-gun employers are any more respectable. Dirtbags of this sort always find ways to harm others whenever they think they are in a position to do so. They care about nothing more than gain and power, with no moral considerations.
We fundamentally disagree on this point, this idea of unfettered freedom of contract. I see value in placing reasonable limits, and value in using force against evil men to stop them from abusing others.
We dont live in your voluntarist utopia. This is the real world. If nobody does something to stop these evil men, they will not be stopped. You are too busy concerning yourself with ideological purity to do what needs to be done.
These are bad human beings we are dealing with, the kind who will use your morals against you to get what they want, money and power, and mostly the latter.
I dont think any amount of reasoned discussion can resolve these philosophical differences, so we will have to just agree to disagree.
