Is Physical therapy worth it?

I am close to transitioning out of the military and am looking at physical therapy for my next job. I loved being a personal trainer and spent the last few years as a firefighter and I really enjoy helping people. I see a lot of people saying PT is not worth the squeeze and it makes me skeptical. I know schooling is pricey but i fortunately have the GI bill and so I won’t have to worry about the financing. Is it worth it if the price of schooling wasn’t a factor. I also don’t have a great gpa and am curious what realistic gpas are for PT school acceptance.

Well after reading all your well crafted comments. I’m gonna look into PA or DO schools possibly psychology. Thank you all for your responses
