"Dow's streak ties record from 1927..."

As The Butterfly and I get ready to start investing (woo, we're like, so grown up), I'm obviously pleased that the market is doing well. That said, I'm finding it very disturbing that inequality continues to grow, the dollar's not exactly dominating, and instability is still hanging around...and nobody's mentioning it. It's boomtime!! Bull market!! Dow 36,000!! The market was doing wonderfully in 1927 while inequality and uncertainty was being swept aside...and what happened in 1929?

UPDATE, 10:04pm - Then again, I just found this. So somebody is looking at history. I appreciate that.
