We have over 500 000 illegal immigrants living in Arizona. And we simply cannot sustain it. It costs us a tremendous amount of money of course in health care in education and then on top of it all in incarceration. And the federal government doesn't reimburse us on any of these things.

For wide swaths of training and education there are valuable spillovers which mean that the private sector needs support from the government. That is why I have been so determined to protect and grow apprenticeships and put higher education on a sustainable footing.

Universal education is not only a moral imperative but an economic necessity to pave the way toward making many more nations self-sufficient and self-sustaining.

Education is a human right with immense power to transform. On its foundation rest the cornerstones of freedom democracy and sustainable human development.

I still indulge in a glass of wine or chocolate - treats are mandatory. Without deviating from the day-to-day healthy diet once in a while it wouldn't be sustainable for me and that's what I wanted: an approach to eating to last my entire life.

A safe and nutritionally adequate diet is a basic individual right and an essential condition for sustainable development especially in developing countries.

We have got to change our ethics and our financial system and our whole way of understanding the world. It has to be a world in which people live rather than die a sustainable world. It could be great.

A rise in the level of saving can reduce aggregate activity temporarily but only a sustained high level of saving makes it possible to have the sustained high level of business investment that contributes to the long-run growth of output.

In the coming years if not sooner social media will become a powerful tool that consumers will aggressively use to influence business attitudes and force companies into greater social responsibility - and I suggest move us towards a more sustainable practice of capitalism.

Perpetual devotion to what a man calls his business is only to be sustained by perpetual neglect of many other things.
