People of all incomes need a budget. Just look at Michael Jackson if you want proof of someone making crazy mad money but dieing up to his eyeballs in debt. Why do you think he was touring at age 50? He was out of money and all he could do was go back to work.
If you're spending more than your making over the long term, you've going to run out of money, no matter who you are or what you earn.
I've never set foot at a Value resort and likely never will. DH would divorce me if I tried. I doubt I could get him to stay at a moderate, though I'd like it just fine. That's not because we're snobs or anything, it's just not what we want in a vacation. So we work our butts off to pay for nicer diggs while traveling. Eating out is important (for lack of a better word) to us as well, we eat one sit down a day while on vacation, and counter service for the other meal (we usually don't eat breakfast, two meals a day and maybe a snack works just fine). I cook 51 weeks a year, part of my vacation is not cooking at all. But other's don't see it as a chore, or can't go for as long (or at all) unless they cook some or all of their meals. And that's fine too. I'd never in a million years look down on anyone for doing that, by either choice or necessity. Just as I don't like people calling me cheap for driving a '98 Saturn. It runs, it looks okay, it's fuel efficiant, I drive maybe 20 miles a week, what do I need a new car for?
And as it's been discused in other threads, what you earn doesn't mean you're wealthy or poor, it also depends on where you live. $100k in my area, Chicagoland, is decent money and can afford a solid middle class lifestyle, as long as you budget carefully and don't splurge too often. $100k in NYC?

I don't even want to think about it!
Right now, the BB is helping me stay on track to pay off our wedding debt. We plan to be consumer debt (CC's and auto debt) in about 18 months or so. After that, we want to save up so DH can afford time off for knee surgery and so we can have a 8-12 month emergency fund. Know where we'er going once we meet all these goals? Two weeks at the Poly, baby!
And I'll be on the Budget Board the whole time we're paying down debt and saving up for our goals.
