I have also found this to be true- a few years as a NUK Officer on a US submarine taught me well, I still remember lessons I learned from junior enlisted, to chiefs all the way up to the captain- everyone expected, some cases demanded- your best. It sets your work ethic for the rest of your life.
That is why this situation bothers me so much.
I think about how many other people, of all races and economic stations in life, got that leg up on success in life because of what the military service they had imparted on them.
And I think of how that has benefited our country, and how many people are missing out on both making our military better and improving their lives.
