It's only cheaper because it's heavily subsidized by the rest of us. Imagine if you only had toll roads, and there was no subsidy on gas. If you like suburban living, more power to you, but don't pretend that it's inherently cheaper when your lifestyle is being subsidized.
Where exactly did I say anything about my preferences? Nor did I say anything about subsidies. Of course cities subsidize suburbs, so what, not in the least bit relevant to any point being made. Subsidies or not, land/house outside a city will always be cheaper than land/house inside the city, that's the cheaper being referred to and that applies with or without subsidies and with or without mortgage deductions.
Beyond that, we live in an age of remote work, don't assume suburban living requires commuting to the city, it doesn't.
I'm not assuming it's inherently cheaper, it is inherently cheaper and always has been. City living always costs more than living more remotely and that's unlikely to change.
You say that it is inherently cheaper, then acknowledge that it is heavily subsidized.
And remote work is nowhere near the level where you could bring that up. The vast, vast, vast, vast majority of jobs still require you to go to the office.
