They could join the military to travel the world. Military paid less, but I have been to a lot of countries after 22 years of service...
One of my (many) mistakes in life came towards the end of my service in the US Navy. I was due for discharge to the reserve in October of '64 after a three year "Kiddie Criuse". I was offered the choice of early release in August, or a six month extension as my ship was scheduled for a Med cruise and would be away by October. I took the early out. So now, if I wanna see Europe, I gotta pay!
