Respond sarcastically to someone who suggests that all 18-year-olds should be able to afford to buy a house and that renting is dumb.
Wow! So when you were 18 you were able to buy a house? I guess every 18 year-old can too and then all these property owners who rent their places out won't be making money because all these dumb renters will be owning now! Genius!! Just genius!
