re "pro-slavery" specifically that seems very clearly intended as a hypothetical argument in response to someone else; e.g. you can imagine an argument about whether you ought to raise the minimum wage where one person points out that someone on minimum wage can't even afford to pay rent and purchase food, or something.

The rest of it sounds extremely sarcastic and tongue-in-cheek. It's also (all of it) more than ten years ago. I think it's a bad idea to judge someone on the basis of a handful of out of context tweets like this.

Stuff like

> Justine Tunney is petitioning the White House to make Eric Schmidt the "CEO of America."

seems clearly like a pointed act of satire by someone who thinks corporations have too much power.
