Its bullshit. If most of you did your studies, you should know the relation between what's in the past and what have right now. The wealth of those big 500 companies between the past and present are different too. Definitely those big companies are trying to PRESERVE THEIR POSITION AND PREVENT CHANGES. You guys should read up on the past and current top 10 companies in each of the different sectors and realise how nasty these current big companies are - to prevent from getting overwrote.
