He holds a degree from a third-rate private university. Private university is where you go to school in Argentina for when you don't have the chops for public university and need to go to a degree mill.
His doctorate is from another bullshit institution made up by a rotting old landowning oligarch who holds prehistoric beliefs in just about everything.
