If you think that this change in retirement plan is going to result in you, or anyone else, ending up with more hours in your logbook, bombs to drop, good deal CCXs to go on, or per diem in your wallet then you're living in a dream.
And the 83% aren't "winning" anything. They're simply getting a SLIGHTLY (a very slight) better version of the TSP masked as a replacement for their pension. First of all, good luck getting an 18yo or 19yo AN or SN to put away money for retirement so they'll "leave with something" when they're pulling in a solid 30k a year. They're more likely to "leave" after 4 years with a car they can't afford (read: debt) than a TSP account that's full of money. And IF you somehow do get the vast majority of young enlisted to invest, then them leaving the Navy after 4 years with an extra 500$ that the government put into their TSP is an absolutely laughable way to frame this as a "good deal" for them.
