i remember we had a guy similar to this come to my college, with basically the exact same story. our guy was so annoying and they made us read his stupid book about how military school makes you an amazing person or whatever and nobody liked it so it was completely pointless

i'm honestly not really a fan of these types of speakers because i feel like they generalize their individual experience to everyone when it's really not always the same.
that said i do understand the problem with urban schools, but i think it's a deeper issue than just them not trying hard enough (that might be a factor in it, but it's not the whole issue)
