> imagine a couple, 65, retired, paid off their mortgage, paid income taxes all their lives until retirement, now living off their savings. It's unfair to start taxing them based on the value of the land their home is built on, which they already paid for. Taxes don't end at retirement. I fail to see how this substantially differs from any other change to the tax code. The retired couple if your example had the opportunity to buy real estate that most young people today will not have. Those same young people have been paying into a social security system that they will be lucky to see much if any payout from. So what is "fair" here? Is it really fair to let those young people pay higher rents so that the old people don't face the challenge of moving to a new domicile? Indeed, those high rents directly finance the mortgages of property owners and thus increase the speculative value of the property, enriching the very same elderly couple that you are worried about being unfair towards.
