And You Can Too(Lets be honest though, you probablly can't)

I'm beginning to realize what these books are all about and the fundamental misunderstanding authors have when writing them.
Please note this is a broad sociological fact and not anything that reaches down to the individual level.

Authors subscribe to the convenient idea that anyone can do anything. This is not surprising as we are taught this as children, "You are SPECIAL" and "You can be ANYTHING you want to BE!" are common banners littered throughout public schools. This message is fine in school as children will usually not keep at something if they don't seem to show an aptitude for it.
This message extrapolated to it's logical conclusion(you are the same as me and can do anything I can do) is a dangerous message among adults however because people don't understand that they really do have fundamental differences.

The plain fact of it is this: Not everyone can understand everything. I suck at math, and can't do much with my personal finances without a spreadsheet to do it for me. Of course, I know how to program that spreadsheet but I can't even do so much as the basic addition in my head. Conversely my uncle is fantastic at monetary matters and math, but still uses the AOL browser, and believes he has to pay for e-mail.
So a book marketed to everyone(which is fine, you've got to sell books so it doesn't matter who reads them) that told people they could start a web empire with a few books on coding and a weekend is great for me, but a complete waste of time and energy to my uncle. Whereas a book on investing where you only need 5k and a weekday is great for him, but a waste of money and time for me.

The efficacy of these books is questionable at best, harmful at worst, unless you are a SMART PERSON. Now, it's very hard to determine if you are a smart person unless you've been given the opportunity to think using another person's brain(in which case, you probably are.)
We all THINK we are smart people, we all believe that our opinions are correct and unassailable by our opponents and of course we can't think otherwise, or our opinions would change.
