The cost of a home is a factor of nominal values, taxes, interest rates, inflation and human sentiment. Every economist would like to make such bold one-to-one claims. It isn't that simple. When you say such things you diminish your credibility.
This piece is better than your last one but YOU'RE STILL TOO EMOTIONAL.
All you end up sounding like is a bitter person blaming the rich for your problems. You attract that audience.
I don't believe that's your goal because you obviously think about this stuff deeply and again, have some great points.
Taxes = Social Values.
In the U.S., at least, taxes favor home ownership because Americans believe owning a home should be a goal of its people. Not everyone agrees by the way.
When you use those tax breaks to subsidize buying a home for AirBnBing you're making it more difficult for someone else to buy a home because they must make up the difference in their wealth from renter to owner plus owner to 2nd home owner. AirBnBs aren't hurting you because of corporations as much as your wealthier neighbors. It creates greater housing inequality between you, a renter say, and existing owners who are using tax breaks to borrow on their existing home equity to buy a house to rent. Artificially low interest rates also favor those owners over you.
In the end, I don't believe the economics will work out and it will damage society. YOU SEE THIS ALREADY but you're crying wolf early.
Another way to put it is AirBnBs create a type of money laundering, which is a another way of putting what you're saying.
If you remove all your attacks on the rich and corporations, etc, and focus on your core arguments about the social costs of AirBnBs, about how existing tax and monetary policies split society between 2-house owners and renters (with no middle) I believe you'll keep more thoughtful readers.
Keep up the fight!!!
