Paul Achleitner quotes:

A Facebook message will never be able to replace face-to-face interaction.

For more than 3,000 years, China and India accounted for half of the world's economic output. But then the Industrial Revolution gave North America and Europe 150 golden years. If you take the long-term perspective, our economic dominance has been more of an exception than the rule.

The problem with our Blackberry society is that hardly anyone has time anymore to have an unhurried discussion about the long-term developments that will change our lives.

Facebook and other social networking sites are bringing together spheres that used to be separate. People no longer have private and public lives; the line between the two is becoming blurred.

The heads of leading American universities say that if they selected applicants based on grades alone, their student bodies would be 100 percent Asian.

Asia has an army of low-wage laborers to thank for its economic boom.

Enormous forces are affecting the world, and we can't possibly overestimate their importance. These include demographic developments, climate change, digitalization and the rise of Asia. And then there's the most important one: the end of a life lived on credit. We must finally free ourselves from debt.

Germany's population is getting older and older and smaller and smaller. To be able to finance our welfare system over the long term, we need more women in the workforce, more children and more immigrants.

Debt is not intrinsically bad. But I make clear to my children that they should only borrow as much as they will be able to pay back.

Everything that individuals ever say or write can be used against them at a later point.

It's completely legitimate for a company to continue striving for growth and higher profits. But business activities have to be conducted in a sustainable manner.

Since loans are getting more expensive and there's less money available, we're seeing a commensurate decline in growth. Higher costs and lower growth, in turn, translate into lower profits. Figuratively speaking, in the future, we won't be able to run as far or jump as high as we used to.
