The National Association for College Admission Counseling [1] isn't doing college-level work, offering "Debunking Myths About the DREAM Act: A Response to Rep. Lamar Smith" [2]. That anti-American bill would let illegal aliens take college educations away from U.S. citizens, and they offer their support for that anti-American bill with an attempt to respond to the Smith article here. They say:

[The DREAM Act would not] result in the loss of "seats" at colleges and universities for other students. The capacity for the American higher education system to absorb additional enrollments is far from being exhausted. In fact, even in the realm of four-year colleges, space is plentiful. Each May, our association publishes a list of between 200 and 300 four-year colleges with space still available after most students have already made their decisions about where to go to college. While much of our nation’s popular focus on "college" is, in fact, on the most highly-selective four-year colleges, the truth of the matter is that there exists a full range of postsecondary institutions which, taken together, will continue to have space for students well into the future.

Perhaps someone would like to take a look at one of their lists and point out other problems, but for now let's play along. Assume there are two types of college educations: one at the first set of schools (the ones that are filled) which we'll call "Wanted", and the other at the second set of schools (the ones that still have room) which we'll called "NotWanted". The NACAC would open competition to all schools to illegal aliens, and if even just one illegal alien gets into a "Wanted" school, they will have either deprived a U.S. citizen of a college education entirely, or they will have forced that U.S. citizen to attend a school in the "NotWanted" set. Of course, it won't work that way: hundreds or thousands of illegal aliens will be admitted to "Wanted" schools, forcing hundreds or thousands of our fellow citizens into the "NotWanted" set. Add in affirmative action and it gets even worse: Hispanic illegal aliens might be favored over lower-income whites and Asians with similar academic qualifications.

The bottom line is that the DREAM Act is a test of loyalty. Who do you stand with, your fellow citizens, or with foreign citizens who are here illegally? The NACAC is on the wrong side.

Discussing how the rest of it is wrong is left as an exercise.
