I guess it's all relative too. As I get older, my salary will increase as well, along with the cost of living. And if I look at my investments as a percentage of my salary, rather than a fixed annual amount, then it makes everything look alot better.
But think about this. Wether you like it or not, the day will come when a McValue meal will cost you $20.

People will say "Shit son, I remeber when gas only cost $2.00 a gallon. and $20 got you a lap dance". Yeah, that's what I'm going to say to my granchildren.
