This came off offensive to me. Kids and a house may not be your ideal life, but many people have that life and don't consider it "lame ass". Some people are actually happy and not constantly regretting roads they didn't take in life. I'm wondering if you're the one who is insecure and depressed.
"Fuck 'em" just means "Question everything and don't let others dictate your values". The author is thinking out loud about something that we all know but are uncomfortable thinking about: The idea that we are not living to our utmost.
It's all relative and subjective though. Case in point, I'm sitting at my desk at work when I'd rather be having a picnic with my family and relieving the burn out I have after a long week. I'll be sitting here day in and day out until I retire so I consider this a bit "lame ass" to be honest. But it could be worse. At least I'm not scouring a mountain of trash for scrap metals in a 3rd world country.
We should all be insecure and depressed from time to time. It jars that thing in us that helps us grow.
