I think it's unfortunate this has been downvoted; I think that many people feel the same way you do. It's probably worth thinking about whether your colleagues' life is really as easy as you think it is. What you see of them is probably them at their best; you probably don't see their hidden financial struggles or family struggles or professional struggles. Most people don't talk about anything like this. So personally I think it is brave to ask this question and I wish I saw topics like this discussed more often.
