Has China's economic boom truly helped China?

With a new and ever-changing civilization, the face of China seems to be getting stronger. It's economy is consistently improving the nation and its way of life. This economic boom has equipped the Chinese with trains that run at around five hundred miles per hour, a supercomputer so powerful it demands twelve megawatts of power, and of course nuclear weapons.
However, that is the part of China that is changing, making the news, and by the sea. China is an enormous country, like the US, it has vast countryside, laced with plains, deserts, and not to mention the mountains. The inland China remains mostly unchanged. It has at least 150 million people below the poverty line, which is nearly half of the people in America.
In conclusion, the boom has helped those in China that live by water, much like the industrial revolution of the 1800's. However, for those that live away from the ocean, they have yet to see any benefit from this development. Will China reach out to its own starving people?
