You should read this New York Times story about Mitt Romney's Bain Capital retirement scheme:

In what would be the final deal of his private equity career, he negotiated a retirement agreement with his former partners that has paid him a share of Bain’s profits ever since, bringing the Romney family millions of dollars in income each year and bolstering the fortune that has helped finance Mr. Romney’s political aspirations.

The arrangement allowed Mr. Romney to pursue his career in public life while enjoying much of the financial upside of being a Bain partner as the company grew into a global investing behemoth.

This is important, because it makes Bain Capital a live issue for Mitt Romney in this campaign, not something he did in the past. Bain makes a lot of its money by liquidating businesses and laying off employees of businesses they acquire, and Mitt Romney makes his fortune from Bain. If Occupy Wall Street continues to be a force through the general election, this could permanently tie Romney to everything that the 99% hates about the 1%.
