lastly, i don't think your analogy to casino success is a good one. there is no luck or skill involved in becoming financially literate and making sound decisions with credit. it saves me a few thousand dollars per year and anyone can do it with a little bit of discipline.
Of course there is luck and skill involved in claiming you can beat the banks at their own game. They have set every rule up to profit very, very, very nicely off of you. If any substantial number of people were beating them, they would change the rules.
And you don't seem to have taken the time consideration into effect either. How many hours total have you plugged in to becoming "financially literate" in the sense you describe? How many books you read, videos you watched, seminars you attended? How much shopping around you done for rates, time spent managing accounts? Because it wouldn't take very many hours before a $1000/year return on that work didn't look so hot anymore. And with the # of books sold and seminars run and blogs written and videos posted and options available on the subject, it is clear that a lot of people are spending a LOT of time of it. Do you know what % of American working hours are now devoted to financial services? It's insane.
All hours that could have been spent working to actually make something that matters, or better yet serving your community.
I'll tell you how many hours one needs to spend to know not to go into debt. Zero. Don't got to read a book or take a seminar or shop around for the best rates or anything. Gives you your day, your mind, and your account free and clear to do what you want with it.
