I think most countries in EU provide free higher education but they rely on America for defense.
I knew I couldn't afford college, but it also wasn't the main reason why I joined. I joined the Marines when I could've joined any other branch, too. The stories recruiters had made every other branch beside the Marines sound a bore. And I can pretty much affirm that I lived 20+ years of life most people may have in my short 1 enlistment career.
In retrospect, we're all paid the same and the job was arguably easier on the Air Force side. If I had joined the AF, I would probably still see myself in it to this day until I was old and frail and they had to kick me out. I see that as basically a multinational corporation that allows you to relocate just about anywhere after some time or get on a duty to do a humanitarian mission or something or go to practically every country in the world during service, for service or on leave (vacation) since you'd be in or so close to travel friendly busy and cheap hubs.
You still have to save but the Gov matches funds.
When I joined, you had to pay $100 per month for 12 months to be eligible for the Montgomery GI Bill (free school essentially). There has since been The Post 9/11 GI Bill and opting into that one is free. So if you joined when I did, or prior to that, and opted to use the GI Bill over the Montgomery GI Bill when you got out, you would get your $1200 back at the end of using the 9/11 GI Bill. So, I got my $1200 back as I used the 9/11 GI Bill as the benefits were extremely different pre-2016ish(?). Unfortunately for me, I didn't know that you could still use the Montgomery on top of it if you didn't accept the refund, so I could've easily got a doctorate.
If I went to school on the GI Bill now, I wouldn't have been able to pump out an MBA though. That's because I was getting paid at a state rate for housing/rent of where my school's headquarters was, and not where I physically was. The difference between that and now after the change is $1100/month. I don't know why that changed, but I do see how that is kind of problematic and the government could save money by eliminating it as someone could study in the cheapest place in the world remotely and collect a ton more to live up life every night like a king.
Little misconception there and not really common info, but it is now free for all those that join.
