They are probably trying to bring the "gated community" concept to the apartment block level. Gated communities are a very bad sign; outside the US, they are usually found in places where income is very unequal, crime is high, taxes low and public services of very bad quality or inexistent. It doesn't have to be like this. In fact, a more balanced society improves the lifestyle of everyone, including those who make more (and end up paying more taxes). Before I'm asked "citation needed", try and imagine which societies I am thinking of.
