It is a very dangerous and naive game to
1) 'Inflation adjust' asset prices (if you think the average stock-holder has anywhere near the spend patterns of the CPI basket, boy howdy do I have something to tell you about home ownership and income inequality: rent is 33% of the CPI bucket and that's an 'imputed cost' for the vast majority of stock-holders who own their homes)
2) Think 7.5% in 2 years is a 'bad return'
EDIT: Let's actually play a fun game, what's the real return of the SPY from the perspective of someone planning on taking a trip to Europe/The UK/Japan?
