I spent about well over $400 just this weekend. 2 new tires, oil job and A/C tuneup. However It's not about how rich you are, it's all about how you manage your money and the county you choose to live in. You must have more coming in than what goes out and take advantage of any opportunities instead of ignoring them, it's pretty simple.
I'm always amused about how most non wealthy people are afraid to reveal what they actually take home per week, like if you ask them you get that uncertain look lol. But I make $17 an hour. My wife makes $11.53 /hr. We both have near perfect credit rating, or as perfect as it gets I guess. My house of $80,000 that I bought in 2007 will be paid off in about 2 or 3 weeks sometime in June. My 2012 Honda Fit is paid off. I'm typing on a MacBook Pro. My PC has an 8700 i7/1080gtx. I can buy for the most part, what I want. It's not hard but you just have to pay attention to money management and take advantage of financial opportunities that accumulate good credit or value. For example, 5 yrs ago we took out a $13,000 dollar loan that had such great interest rate to pay off something of higher interest and we pay bi monthly and more than we need to, to keep that interest down. That loan will be paid off in a few months, saving me thousands. There's also all sorts of help programs that crop up from time to time that can be taken advantage of, just tons of savings assistance programs from various groups and banks.
