Mandatory + Unpaid = Freedom?

Right-wingers are always droning on about how they're the party that truly values freedom, because left-wing regulations take away your freedom to exploit others. What they always forget is that those being exploited are having their freedom taken away.

This is just one example: a coal company forcing its employees to attend a political rally, without pay. Making anything "unpaid and mandatory" is unethical enough; doubly so when that thing is a political rally. What next? Forcing them to vote a certain way? A right-winger would argue that this is "true freedom" because the coal CEO is "free" to force his employees into political rallies, and cracking down on this would infringe on such freedom. By that logic, a dictatorship is the most liberating form of government around, because by god that dictator gets to do WHATEVER HE WANTS!

I'll spell this out: the "freedom" we're supposed to protect is the ability of individuals to live their lives as they see fit, not the ability of a select few to control the lives of others. The coal CEOs can go to the goddamned rally themselves; THAT's freedom. Forcing others to go to rallies; forcing others to drink polluted water; forcing others to receive shitty pay for dangerous work: these are not freedom. They're acts of tyranny. And it makes no difference whether they're committed by a government or a corporation; they do equal harm either way.
