Big nick does your name signify that you have a big penis.
No, It was a nickname given to me a long time ago by friends and it stuck. Yes, I get asked this question a lot. No, that is not the connotation of the nickname. And no, I won't tell you how big. Unlike many guys, I don't feel the need to constantly talk about my size.
Last I looked, Enslaved Labor is still available--but it was moved to the Manipulation (diplomacy) tech tree. Here's a YouTube clip for you from a very funny cult classic movie that's probably way before most gamers' time:

Here's one of the funniest movie scenes of all time from that same movie:

Nope... It's gone on the Vasari Rebels. But it is still there on the Vasari Loyalists.
If you do the math, that discount (4% per level) actually takes a while to payoff...not as bad as some techs, but still, it's not the end of the world...
Except you're forgetting that the Vasari have the worst passive economy in the game. They make their resources through warfare. If you're not fighting, you make very little money. The TEC and Advent both have better passive economies than the vasari. So not only do they have the worst passive economy, they have the most expensive units and structures in the game. So other than combat, guess what the only other economic tech the vasari had was to balance their economy with the other races. You guessed it... Enslaved labor. Sorry, but no. Enslaved labor or an equivelant tech should be back in.
