Private schools have more leverage on whom they will accept as pupils and hence can target an "easier to teach" part of the overall pupil population. To me the Swedish system is the worst of two worlds: in Germany, there are good public schools for well-performing students; the problem is that affluent parents typically make sure their children are classified as "well-performing" (roughly speaking; there is a lot of wiggle room). This is somewhat unfair, but facilitates to some extent the development of pupils with reasonably high potential. In other Scandinavian countries, the state provides enough resources to have small class sizes in which pupils of all abilities get educated together. This is fair but can hamper the development of high-potential children (teachers still have limited time and attention). In Sweden, the distribution of resources as criticized by the article facilitates that pupils in need don't receive special support and high-potential children get their education in for-profit institutions for pseudo-elites where a teacher is discouraged to give tough feedback because it can hurt the organization's bottom line.
