FWIW I think in the last couple CBA cycles that's not as true as it used to be. The reasons it has happened are far from noble, but the luxury tax and especially its draft penalties has been a real spending deterrent, FA classes get slimmer and older each year, player development makes it easier (relative to the past) to improve lesser players with the right instruction(which is not expensive), and draft/IFA pools have shut down avenues of buying talent. Go back to since the start of the 2017 CBA and you've got about 6 full seasons. The Top 10 in wins over that span include Tampa, Cleveland, Milwaukee, Minnesota, and St. Louis. What smaller markets still don't have is as much cushion from being very bad.
