Lets examine the things most adults need to pay for.
Rent/Mortgage
Insurance (health/car/home)
Food
Clothing (and I'm not talking about designer)
Utilities (just the basic heat, electric, water, sewer) will set you back several hundred dollars a month.
Car Payments
These are just the basics. And of course for those with families/children those expenses are multiplied by how many children you have.
Retirement Savings
Emergency Funds Savings
College Loans (not everyone, but many, many do)
Savings for children's college funds (for those with kids)
These are the things most people need to save up for, or pay to have a secure future.
It's not just about being materialistic, it's about providing for yourself and your family.
