> Cause free labor's the cornerstone of US economics

The lyric is alluding to the fact that the country's foundation was built on 100s of years of free labor.

The practice of exporting worthless printed paper in exchange for valuable labor intensive goods is also what that lyric is pointing to.

American slavery, a model that has evolved and now encompasses much of the globe.

Keeping a large % of the world and "undesirable" domestic population poor, at gun point if necessary, is in America's national economic interest.

You need to argument when you negate someone's opinion.

Do I also need to argue someone's opinion of the earth being flat?

So what you're saying is that statement you negate is based on your opinion and not on any factual information?

What I'm saying is that not every opinion deserves to be taken seriously enough to merit an argument. There are plenty of opinions which deserve mockery and contempt.

> There are plenty of opinions which deserve mockery and contempt.

Such as your opinion.

So, you do agree with my opinion.

Yes, kinda? I mean, we basically replaced slavery by machine work, no? Its "free labor" as machines do not try to escape, and are fed with stuff we find underground so they don't compete for our food.

I don't think slavery would have been abolished without the industrial revolution.

> Its "free labor" as machines do not try to escape,

That is most certainly not the usual interpretation of free labor.

The overwhelming majority of slaves in the US were field hands in plantations growing cash crops. How exactly did rudimentary agricultural mechanization around the time of the American Civil War in any way precipitate abolition?
