Excellent, thoughtful post. Who let you in?
As for the unlimited growth of sharps from squares, it ain't going to happen.
1) Their IQ's aren't going up.
2) Recreational players don't have the time (or interest) to invest to become sharp.
3) At small betting amounts (budgets of most non-pros), the investment of effort would not be worth the return.
4) Some people will always play their home team (or Notre Dame) no matter what the spread and still think they can hit 8-team parlays and teasers.
5) New squares are always coming in. So even with a former square becoming sharp after a few years, there will still be new squares and even inexperienced sharps entering the ranks.
6) But most of all, the industry is filled with a bunch of sick, greedy, degenerate bastards (and they're damn proud of it).
1,2, and 4 are the main reasons why this will never happen.
