That general sentiment is unsupported by evidence and most of the time when you challenge it you get links to strongtowns.org which is a non-credible source run by a crank.
People constantly say that cities "subsidize" suburbs but when you look into it you find out that is only sometimes true, and that many of the people who do the most productive work in cities commute there from the suburbs, and that many of the world's most valuable companies, including all but one of the FAANG companies, are located in suburban areas.
Plus, if people really want to talk about "subsidies" they should admit that big dense cities get plenty of those too.
You'll also see a lot of commenters who think "suburban" and "rural" are the same thing, often without realizing it, to the extent that one particularly clueless comment I saw recently asserted that nobody in the suburbs had city utilities and all the houses had septic tanks.
Cities are actually very expensive to maintain, and they tend to have the worst concentration of problems such as crime and drug abuse, and NYC is one of the prime examples.
