But there are a number of studies demonstrating how race & class impact things (when controlled for other factors) like teacher perception, grading, letters of recommendation, not to mention just the fact that if you are growing up in a black (or white) household that has $5 in wealth, you'll have less access to educational opportunity than the white (or black, albeit far more rarely) household with $200,000 in wealth.

We shouldn't seek to control for these factors?

No. That only tells you to fix those factors but the outcome is what they are. By the time of the ACT/SAT test it's too late to fix those things. Fix those upstream.

Based on?? If someone is smart, but denied opportunity, often times this can be resolved by exposure to things - even for an 18 year old.

Indeed, environmental factors become less important for intelligence starting precisely at this age.
