Hardship is relative. There's always someone who's had it harder than you. His parents sacrificed things to get him the resources he needed to succeed, is his point. They sacrificed things that the parents of other kids did not.
People are starting at different points. His parents were physically able to do what they did. If his dad had been disabled, or dead, he wouldn't have been able to commute for 4 hours. Would that make his dad less virtuous?
