Pretty much everything costs more now. I'm not just talking about inflation, I'm talking value.
Want to own a home? Well it's exponentially more expensive today than it was in the past. Pay for college? While it was possible to work summer jobs back in the '70s and '80s to pay for a year of tuition, that's not happening today.
It also doesn't help that property and income taxes are increasing, and if you want health insurance for you and your family - a portion of your salary's going to get deducted for that. In many cases, you're still going to front a percentage of the costs, which are insanely high compared to the rest of the civilized world. So what's the average person who doesn't happen to be rich do when they finally want to retire?
