That's very commendable.
Yes, the discussion was about money in general, not just where it comes from.
I have a feeling that many people confuse luxuries with basic needs. Like you say, some people think it's only natural that they "need" a big house and car.
It's difficult where to draw the line. You can live in a small house, you can use public transportation. Actually, any means of transportation other than your own two feet could be considered a luxury. But when does a house become too small? When you're a couple with four children, say, and you have to live in a one-bedroom appartment with bad heating and plumbing, is a larger residence really a luxury?
Suppose I won the lottery or something, or received this crazy inheritance, or whatever. I still wouldn't go for the "big house with pool" or "jacuzzi in the back" car. I think I'd really quit my dayjob and go after those dreams. Perhaps in a flash of altruism, brought on by the adrenaline and endorphines of coming into all that extra wealth, I might even help out some other people. What we do with our money is partly dictated by society as much as by personal choice, the thing is to find that harmonic balance and perhaps that's where so many people go wrong, like those guys who keep buying extra stuff while they should be paying their rent or feed their kids.
