What college kid made $6/hr. In 1979? That would have been extremely rare. $4 to $4.50 would have been good. If they could have even found a job, and many could not. Remember, it was 1979 and Jimmy "the disaster" Carter was president.
The Senator said he was making $6 / hour. Not me.
Even if it's $3 hour -- which was about minimum wage in 1979 ($2.90) -- it's still the same - back then, you could work a full time summer job and earn most of your tuition, room, and board for the year.
Now, forget about it.
