I worked a job that had me interacting with troops on a bunch of bases in the very late aughts, and I often heard from joes “bro do not join the military I did it because I was high/drunk/broke/911 happened and i joined the next day/couldn’t find a job and I have regretted it from day one”. None of the joes I ever interacted with came from comfort or money, but I only interacted with low level people.
