Are they rich now? One would think...
They should be, unless they've been unduly profligate in the last 12 years (which is doubtful, as almost every rich liberal is as crabbed and miserly with their own money as they are liberal and spendthrift with everyone else's money). According to the Wiki
article on Frau-bee_itch Blades (which I'm sure is a reasonable enough source for a data-point like this) Blades and Boyd sold the business they created - Berkeley Systems - for $13.8 million in 1997. Since Berkeley Systems was founded in 1987, they no doubt scored mostly long-term capital gains on that sale, which means they should have paid no more than 20% in federal taxes, which would max out at about $2.76 million (assuming no basis to recover out of the sale proceeds), leaving them with at least $11.04 million net of federal income taxes (the fact that I get so close to a round number with that tax estimate makes me believe that they really sold for $11 million, plus a tax gross-up).
If they're as miserly as I've heard Michael Moore is with their own money, then that $11 million would be worth today between about $16 million and about $29 million depending upon what they invested it in.
So, yes, I'd say they're rich - they just don't want any of the rest of us to be rich (it's no fun being a rich white liberal if you have to constantly worry about being overtaken by the hoi polloi - particularly the coloured hoi-polloi).
