If you don't believe, just calculate how much money LL is now making off the lindex whenever day traders get involved (when they buy, it doesn't go to their CC remember).
And if LL is making more money, that money has to come from *somewhere*. They haven't disovered a secret money making machine, my friends!
Basically they are taxing the lindex and the economy 3.5% everytime someone does a market sell and sells to a day trader.
