it's a matter of cost-of-labor and population density.

I heard that railway systems in most countries are not profitable, they have to be funded by the government.

But the Chinese railway system is so advanced and profitable, due to cost-of-labor and population density. Even high speed railway wasn't a Chinese invention. As a comparison, the U.S. railway is so old and kinda desolate.

Most ideas are not originated from China, but they grow better in China.

Because of the population density, the network effect is stronger in China.

There's also the fact that China is not as burdened by legacy infrastructure and business models.

For example, consider high speed rail in California. Due to the existing rail system, the marginal increase in economic benefit gained by building a new high speed system is fairly small.

Compare this situation to high speed rail in China. Without the existence of a fairly efficient existing system, the economic benefit to building the high speed lines was massive.

This historical pattern is somewhat common.

Rising societies have all of the latest advances gained by building previous systems, and none of the existing societies' technical debt.

They get the newest and shiniest technological base, simply because they're building it now.

That's only true of passenger rail though--freight rail in the US works really well.
