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.
