Also, speaking to graduating students is far from the most common activity of such professional speakers. The use of motivational speakers at conventions, paid seminars, & sales pitches is much more common & frequent than talks given to students. Since Randall doesn't mention students in any way, I think that specific phrase about students should be removed from the explanation.

:Less wealth than their parents? While it would be hard to compare, I would argue that they mostly end up better, as technological advances makes economy grow. Although it's true that depressions can reverse it. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 00:09, 23 April 2017 (UTC)
 
  
 
This isn't quite relevant to the topic, but please let me vent out about a certain opinion that is going to appear in the explanation eventually: that lotteries are bad investment ''just'' because they lose you money on average.  This is in fact bullshit, because so does insurance!  If you really want to apply math to such things, you need to integrate welfare, not money profit, over the probabilities.  Wherein welfare is some half-arbitrary function over money that denotes its actual impact on one's life and that ''usually'' grows slower than linearly on positive side (your life changes more after earning the first million dollars than after the second one), but sharply drops on the negative side (a bad debt is a life-ender).  With such a welfare($) choice lottery is in fact bad while insurance is good.  Note, hovewer, that in some situations, like when you already have a big debt and the mafia is killing you for it next week, lottery makes a surprisingly good, while still unlikely, investment!  It's all a matter of the specific situation with welfare($).  (Sorry for bad engrish, I never learned all those math terms.)  [[Special:Contributions/172.68.182.136|172.68.182.136]] 20:18, 22 April 2017 (UTC)
