Right, that's why "You really think you have it worse than somebody born into slavery?" is a ridiculous statement. Would being a slave in the past be any worse than being a slave today?
Historically, slaves could be (and were) raped or killed by their "owner." When you talk about "slaves" today, are you talking about someone with a low wage? That's not slavery.
Unfortunately, there is still slavery in the 21st century, but that has nothing to do with the people discussed in this article.
