Looking back, I thought I was rolling in dough as a new ensign, and I was. I will forever be grateful to the Navy for giving me equal pay for equal work, and training me in career skills still paying off for me today. A regular income, with generous untaxed allowances, free medical/dental/pharmacy, inexpensive life insurance, with predictable promotions and opportunities for graduate education and career development - such a relief to me. And fun, challenges and honorable service to the nation to boot - I felt truly rich.
It is all perspective.
Gaining my commission out of OCS straight out of college, I finally had enough income to buy a car (had ridden a bicycle all through HS and college) and get a credit card based on my O-1 pay. Bless NFCU. My college tuition, fees, books and room had been covered by a merit scholarship. My parents bought me a meal plan each semester, paid for the college health plan and put $300 in my checking account every September, having taught me how to budget. I took the Greyhound bus (ugh) home on breaks. All my play/clothes/treat money came from 2 part-time campus jobs and a business I built up myself. Computers at that time were mainframes, and PCs a few years into the future. All pre-Internet and online anything. Students hand wrote their papers, unless they had a typewriter (20th c tech). I saved up, bought a used IBM Selectric typewriter and typed papers for students and profs. Buck a page to type it just as you wrote it. Two bucks if I corrected your spelling and grammar. $25 - $45 for a consultation on your outline, depending on paper length, plus typing fee (packages and semester packages available), but I wouldn't write your paper or do your thinking for you. I threw in a nice cover, and all the footnotes, references, annexes, etc., were professionally done. The profs got to know my work, and I started doing their academic papers. I charged them double. I knew exactly how much I could book and complete. There were plenty of wealthy (to me) kids at my school who had the funds to pay me. I built up my emergency and savings funds, saved up for beach weekends and that special dress, drank a lot of water when friends drank beer, became a creative cook when it came to ramen noodles and box mac 'n' cheese. I graduated from college with zero debt, and though accepted into various grad schools with grants, I took a deep breath and made a huge and unusual course change to head to OCS. That's another story that involves naval aviators, officer recruiters, in summer whites, at an info table in the student union.
I carried on with my habits of budgeting and investing, living within my means but also enjoying life, married someone with the same habits, and we are blessed at this point in our lives.
The point to my sharing this is that the 0-1 full benefits package, along with the skills being learned, lays a solid foundation for both financial stability and career viability, whether staying for the initial obligation or years beyond that. IF the ensign or second lieutenant does smart things from the get-go, and practices discipline when it comes to "need vs. want" decisions!
And, that first car purchase? A genuine ensign-mobile, a taxicab yellow Triumph TR-7. My weakness ever since, budget permitting, after all other short/mid/long-term financial agendas determined to be in good shape, is a performance sports car. I think it's because of all those hours on a bike in HS and college, not riding for fun or fitness, but getting somewhere, whatever the weather.
