The future of China

There are always people only caring themselves, but not the society and the country at all. I sometimes get confused when I hear sb say: life is only consisted of eating, drinking, palying, and having fun. I don't believe in these words, but I can feel their happiness when they are saying so, meanwhile, I find mysely get nothing but pain when I find out how ridiculous the words I was told when I was growing up. Those text books just told us that the reason why China comes to current situation is that it has to be like this, and China can't be a capitalist country. Why? because it tried this before by Sun Yat-sen in 1912, but got lost, so it's destined to a failure. But there were also many Eastern Europe countries turned into capitalism during 1989 and 1991, can this be called that they don't adapted to the socialism? So they are doomed to be capitalism forever? The goverment says no, for that such failures are just some "temporary phenomenon", the ultimate goal is still socialism, and communism. However, why can't we use the same reason to say that the failure of capitalism in China about 90 years ago is also just a "temporary phenomenon"?
The most extensive things you can find now in China are problems, there are problems everywhere, and everyone can see them, but there are few things we can do but just wait.
I don't think I can see a really democratic, free, prosperous and powerful China during my life, I hope our posterity can see.
