True, there are people out there who really are mentally challenged and will unfortunately probably never be able to complete high school. Its a sad but true fact. That said, the VAST majority of people are capable of doing great things. They're just not prompted to do it for various reasons. I almost believe a college education should be a requirement for citizenship. I'm not talking just for immigration, I'm talking for EVERYONE. Born here or not, if you're not educated you shouldn't vote.
