Should the college classes be free for high school students recieving As in previous level classes?

I am seeing that top students gets merit based scholarships. But many of the good students fall in the bucket where they are probably above 80-85% students but does not fall into the top 2-3% bucket who get scholarships. Now Many of these students will end up into good colleges paying high tution inspite of being good. Not only that many of these students take college class while in high school. At least we can make efforts that these students do not have to pay for colleges while in high school as high school is supposed to be free for all the kids. Also it is not that colleges are not going to get money for the credits these students will get for the classes they are taking in high school. Colleges are going to earn more from these students as these students will be taking higher level classes in college. The colleges can have their own assessment to make sure that they qualify - no problem for that. Note: The pct are approx. But if the college confidential administrators or parents who have better statistics can jump in and put more accurate numbers. The goal here is that high school students do not have to pay for colleges. We want the monster(college tution) not to touch the high schoolers.
