Well, I thought you were advocating for changing the law, and doing away with cap gains...so it appears you aren't necessarily in favor of considering everything income then...Capital Gains on houses are not figured that way. Simplified you can roll C.G. into your next house.
Also the home owner gain cap rollover rule was abolished by Bill Clinton in 1997. The rule that replaced it, The new law, allows married couples to exclude up to $500K permenantly, single folks $250K of cap gains...but under your new rule, there is no cap gains....so...
What other loopholes are you going to include?
