I would feel morally obligated to make sure they understood what was on the table

At the end of the day, while FIRE is appealing to me and works well for me, it's not the only right way to live. I think if someone I was close to got set up in a good paying job, offering to explain their retirement benefits to them and help them get set up is fine, but I wouldn't push them more than that because it can seem a little preachy. If they want to know more, then we can talk. Most people don't, and pushing the subject would only be off-putting.

Similar to if I had a morbidly obese friend. Yeah it'd be good if they counted calories and ate mostly fruits and veggies to achieve a healthier weight, but is it really my place to push them towards a different lifestyle? Or should I just be a friend and help them when they ask for it?
