What is a lot of money to spend on......
a Cup of coffee? $4
a pair of jeans? $35
a pair of shoes? Depends on the type of shoe - athletic shoes (biking, hiking, etc.) - $75-100, other $40
Dinner (per person)? $20
Vacation? Depends on the location, but assuming not Central or South America or Africa, then $1,000 (per person per week)
A new car? $25,000 (I don't own a car, so really I think anything over $10,000 is a little crazy to spend on a depreciating asset)
