37 years ago when for the first time working in America, I was amazed at the convenience of its advanced collective utlity especially in libraries and parks. 

Any local resident who fills in his or her name and mailing address on the library post card, and all he or she has to do is going home and waiting for the post card, and then exchange it to a library card.  Cardholders can borrow books, periodicals, visual tapes, audio cassettes, even toys for kids from the libraries.  In so doing, people can acquire knowledge and entertainment from libraries if they want to for free, regardless of how much tax they pay to the government, or even no tax paid at all.  

People can stoll leisurely, play freely, and jug without distraction in the vast parks full of amentities and facilities almost in every single town.  Well, people do not have to own a masion or a castle to enjoy all of these benefits.  

I always think the good use of those collective utilities is one of the best ways to minimize the social gap between haves and have-outs, even in the highly capitalist nation like America.  Now I found an academically-written article, which further explains the concept of collective utility, as attached below, as how to effectively realize the social equality in a socialist China:
