The NCAA and the member schools are not preventing anyone from making a living or making a living playing football. The NCAA has no say on NFL entry requirements.
Similarly, as dpodoll has said the players have every chance to turn down or walk away for the grant-in-aid.
Regarding the power 5 proposals, it almost seems like a miscalculated effort to appease the union/public opinion.
The NLRB decision laid out the bullet points for determining what an employee is (it is a fascinating insight into the wildcat program:

By treating football players differently and allowing more hours for football than academics they are at risk for an adverse decision.
If unions become a reality the lawyers, like the terminator, will never stop in their efforts to increase compensation. It is the slipperiest of slippery slopes.
