If players were allowed to be paid, I think it would open up Pandora's Box
That's the argument everyone uses for any change - ever. That and "oh it will be a slippery slope".
It has a tendency to be just fear and after the change occurs it feels as if the change had been there from the beginning.
and the whole amateur feel of college ball would change
That depends what the changes are - players can still receive $$$ without turning into commercialised machines themselves.
Remember the NCAA is already heavily commercialised...it's just that the actual players have a tendency of being poor.
while the richer colleges would just dominate even more
They already do anyway, the top colleges have the inherent advantage of better programs, more potential to develop and build reputations that will lure the top of the class who aim for the NBA (like Kentucky, Duke etc.)
However, again, it depends what the actual changes are.
Think about every other student at university who spends time studying and in their spare time they work to make money. Some of the top students will have scholarships because the colleges want to attract the best and brightest - these students most likely still study and work.
The college bballers (and other sports) don't have time to work because the basketball is their work. People assume "they'll make all their money when they turn professional"....but most don't turn into professional basketballers! If we only had those playing who turn into paid bballers, college basketball would become significantly smaller.
Looking at the scholarships and allowances they already get - they aren't exactly "living it up".
Given the amount of $$$ that is made from these players, I think there is serious discussion for the type of reform that allows an increased guaranteed allowance of $x for every player of a particular division - so all Div 1 players are played the same, all Div 2 players are paid the same etc.
If it's $5k now, make it $15k or whatever is a more liveable range.
That way, there are no salary cap issues, there are no additional advantage to the powerhouse colleges over smaller ones and there are no commercialisation of players through different salaries or endorsement deals.
