Chinochulo,
This is kind of off topic, but since we are in a forum discussing vehicles that cost more than what a lot of people are able to afford, I suppose it's as good of a place as any to discuss it.
I guess it depends on your definition of wealthy. I do feel like I'm wealthy in my relationship with God and family, but not at all financially. I'm just a HS graduate who's always been a just a little bit entrepreneurial and recognized early on that they only way to earn what you are worth is to work for yourself. With that said, I've had times where I was under the lowest tax bracket and others where I was well over the top. I've had some decent middle income jobs that were great at the time and counted them as a blessing too. In my experience, what seems wealthy depends on where where we are currently at. I've had time where I'd look at someone else with $20,000 in the bank as well off and I've had times where I felt that the number would have to be at least a 1mil or more.
Paying cash for something, in my opinion, is just an indication that you are living within your means. Same goes for your home. As soon as you're able, pay for what you can afford so that you don't have payments and all of a sudden, there's a lot less stress when you know that in order to keep it, all you have to do is pay property tax and insurance. I think of that as living simple and believe that's what we should all strive to do as long as it takes a back seat to the more important things that truly make you "wealthy".
