Citation needed. Everything I have seen shows that suburbs are a net drain in contrast to dense urban areas. Infrastructure has very high fixed costs that require more people to net even.
Citation needed on what you have read as well. I too have read the same, but it conflicts with the reality that suburbs have existed for more than 100 years now, and those old ones have added and replaced infrastructure many times over their history.
That nothing i've read acknowledges that fact suggests they are cherry picking evidence instead of giving an unbiased analysis .
