I generally like what you have to say, even though I don't always agree with it. Your advice is such a great crash course for someone who really doesn't get it. My H was like that. He grew up super poor, and always just spent what he had. He doesn't do that now, and we had to go through a period of what you describe, him complaining and me trying to get him to see how his constant selection of instant gratification wasn't doing us any favors.
Now we're there. Our efund in cash is quite small, because we consider our investments to be our efund as they're relatively stable and sans penalty for withdrawal. We're happy to do things like take on 0% loans for a recent medical bill even though we had the money in cash. We invested the money instead, and are a month away from paying off the bill. We did really well in the market for that money, making almost 1k in gains that we wouldn't have gotten had we not put the money in when we did. We don't mind low interest debt and happily invest over being debt free. I am very into our personal finance, and tweak constantly. I budget to the penny, we don't have cable/satellite, or a home phone. I drive a 9 year old paid off car, while H sold his gas guzzler and now we have a small payment on a fuel efficient vehicle. The payment for the car plus gas is actually less than we were paying in gas for his truck.
So it's not that your opinions aren't popular. I think they're very necessary for a lot of people. I just think they're not for everyone. Most people who migrated to GBCN don't need to be extreme. A lot of people posting here definitely seem to need that extreme DR/Sisu approach. So I'm glad you're here!
