The actual question is whether smart people should receive a disproportionate amount of a finite resource, like education. This imbalance creates a potential runaway effect in which one group grows ever more successful at the expense of other groups.
Source: Am a parent of a G&T student and I see the intensity with which parents push their kids into the program.
Do you have any sources that these things happen and/or that they negatively impact students outside of those programs?
The argument I've heard previously is that G&T programs remove peer role models from classrooms, which lowers the class's average behavior and achievement.
I was a G&T student for 5 years (2nd through 6th) and have close relationships with people who were educators then administrators in a G&T program.
