It's not an obsession. Individual lawsuits would be tedious, 90% of them would not be able to surpass "small claims" status and would not have the desired impact and/or implication of the greater picture. The fact that hundreds if not thousands are being swindled out of there money. A calculated, organized, hit like a class action lawsuit represented by powerful attorneys would finally put this nightmare to an end.
I think you are completely missing the point. What's missing to make a bunch of small claims into a successful class action suit is a) calculated; b) organized; c) a bunch of powerful attorneys; d) a basis for all this.
Simply renaming the collection of small claims into "a class action suit" does not accomplish any of these any more than the re-re-relabelling of US unemployment or homelessness finds people jobs or homes.
I am sure the cost would be minimal as this is a popular subject right now and the media attention alone would be worth thousands to a firm. I also believe that BFL does have some significant assets even if they are hidden I'm sure a group of savy tech people like this one could track down a good portion of those assets.
This sort of "I'm sure nothing that's popular costs anything" nonsense shows plainly you have no idea how things work. For your own benefit (ie to get your brain out of the swamp), compile a list of all the people famous during the '90s, put on one column a "famous index", percentile of fame total as evaluated by you and on the other column their total net worth as a percentile of the total net worth of the world. Or, if you prefer ten zeroes after the point instead of twelve, go with a percentile of the decade's worldwide GDP.
You've not quite built communism yet. The currency of the land still isn't "fame". Why exactly do you think the media can't even afford to pay the sort of clueless interns currently involved?
(Since we're doing research tasks to benefit your education, find twenty successful class action suits, calculate the average litigation costs over the set, divide it by "thousands" and report the multiplier. That's how many times you have to say "sorry I'm lazy and stupid, will do more research on my own in the future".)
