"I swore when I left college (that) I would never go to graduate school. Although I kept to that promise, I've wound up relocating many aspects of academic life in my professional career."
He says economics is also a subject that he reluctantly came to.
"I swore I would never do business journalism but I wound up in India doing freelance reporting. And I quickly came to realize you couldn't understand politics or the social environment unless you had an understanding of what the economic motivations of people were."
One of the major issues with the Chinese economy is slowing growth. The government has set itself the target of doubling the 2010 per capita income by 2020 in the current Five-Year Plan (2016-20), which would result in China being defined as a high-income country. To do this, it has to achieve 6.5 percent GDP growth in each of the next five years.
Some think, however, the government should move away from growth targets.
"They've had growth targets since the early 1980s and it has been a deliberate part of the development strategy. It was a way to motivate local officials and officials all the way up the line. It is similar to what Japan and South Korea did also," he says.
"I think now, however, everyone knows that growth is slowing to some new level but no one can quite agree on what that new level is, or should be."
There is now interest in whether China will soon regain its position as the world's largest economy, which it last held in about 1800.
"All economies were largely agrarian then and all agrarian economies then had more or less the same per capita income. So China with the biggest population had the biggest economy, although it had a pretty sophisticated preindustrial manufacturing economy for textiles and porcelain."
Kroeber predicts in his book that it might overtake the U.S. in size as early as 2028.
"I think in an economic sense what is most significant is not the size of the Chinese economy but the scale of its trade and investment links with other countries. I think the most interesting statistic is that China is now the biggest trading partner of more countries in the world than any other country."
Kroeber rejects those who forecast that China could even become the richest economy by the 2070s.
"I would put money on it never even happening because no other developing country has been able to exceed the U.S. in per capita trends. Japan is the most notable example because it did look like it would in the late 1980s, but it hit a wall. Most countries have flattened out at between 60 and 80 percent of the U.S. level."
