In the real world, one of the most colorblind of professions is that of the modern military.The difference is Lorca is supposed to be a key cog in the Federation's war effort, not someone staring at a panel a few hours at a time to get experience.
People rise through the ranks there because of their training, ability, and hard work. Their skin tone, ethnic identity, etc. are not a factor in their promotions.
In the series that some folks are touting as the torchbearer for Roddenberry's progressive "vision" of a better future, we see the actual progress made within real world militaries being pushed aside so that untrained children can serve on the bridge of the most famous ship in Starfleet merely because Picard was chummy with the child's parents.
Wesley Crusher was not disadvantaged. If his dream was to serve in Starfleet, he could have done it the way that all of the people that were pushed aside for him did. He could have trained at the Academy and worked his way up the ranks. But no, he can't do that. He is too special. He has friends in high places that can get him where he wants to go without having to work for it.
As I said above, Wesley Crusher is a poster-child for "priviledge". The allegedly better ethics of TNG ring pretty hollow to me.
