What is "The Party"?
In theory "the Party" represents the interests of "the people", that is, all of us. We in our societies live by "the core value of Capitalism" which loosely translates to the primacy of money with everything rendered in terms of monetary worth. This leads to awkward kludges when the needs of society collide with the core values of capitalism where we try to make a market in some social good and unfortunately quite often fail at it. We also allow our society to be 'captured' -- purchased -- by capital, a notion what was enshrined in the UK when the "There Is No Alternative" mindset saw off the post-war mixed market. (....and there's a direct line between TINA and fiascos like the London Water Company)
You may or may not like the Chinese way of doing things but its the Chinese way of doing things, its their society and culture and they evolve solutions that suit their needs. You will recall that they tried our model and it didn't work that well -- they refer to the period where they experienced colonialism as the 'century of humiliation'. We don't like their way of doing things because it has the potential to be a lot more efficient than our model since they're able to manipulate capital costs to direct investment where its most needed rather than solely where it generates the best returns for banks and investment houses. Personally I prefer the pre-TINA model because we (in the UK) tried the mixed market post-WW2 because the pre-war model just didn't deliver.
