I used my GI Bill from service 1968-76 and it paid for tuition and some money for books all the way through my time at the North Avenue Trade School. Without it, I’d never have been ablet to graduate in 1980.
I think it was around 76 that they herded us all into the Base Theater to push the “new and improved” GI Bill which required folks to pay into it - I opted to stay under the old one and got my degree with no problems - while others struggled....
That's something I haven't heard in a while.
