We have by far the most expensive health system in the world. We spend 50 percent more per person than the next most costly nation. Americans spend more on health care than housing or food.

I think there's a lot of work to be done with our societies. My biggest passions are the environment and health. And when I say 'health' I mean the secrets behind health and our food system.

Corn is an efficient way to get energy calories off the land and soybeans are an efficient way of getting protein off the land so we've designed a food system that produces a lot of cheap corn and soybeans resulting in a lot of cheap fast food.

It makes sense that we came up with our public school system during the Industrial Revolution because it's like everybody is a factory worker eating their terrible food and going back to the room where you're silent and listening to an idiot. That's an epitomizing idea getting called 'Nothing' for your whole high school experience.

But Australia faces additional regional and global challenges also crucial to our nation's future - climate change questions of energy and food security the rise of China and the rise of India. And we need a strong system of global and regional relationships and institutions to underpin stability.

Local and regional food systems are about opportunity.

Well first let me say that I think health care reform is important. It has to be a priority. And our system is broken. The Finance Committee bill is the best effort yet due in large measure to the efforts of my colleague Olympia Snowe but it's not there yet. It falls short.

As you know Social Security functions under the premise that today's workers will help finance benefits for retirees and that these workers will then be supported by the next generation of workers paying into the same system.

In constant pursuit of money to finance campaigns the political system is simply unable to function. Its deliberative powers are paralyzed.

Unfortunately money in politics is an insidious thing - and a loophole in our campaign finance system was taken advantage of with money going to existing or new 527 groups with the sole purpose of influencing the election.

The FHA's success provides strong evidence that government can and should play a role in the nation's mortgage finance system. It also demonstrates that although government intervention in the economy during the Great Recession was messy things would have been a lot messier without it.

Today if you look at financial systems around the globe more than half the population of the world - out of six billion people more than three billion - do not qualify to take out a loan from a bank. This is a shame.

It is well enough that people of the nation do not understand our banking and monetary system for if they did I believe there would be a revolution before tomorrow morning.

I think however that so long as our present economic and national systems continue scientific research has little to fear.

As long as enough people can be frightened then all people can be ruled. That is how it works in a democratic system and mass fear becomes the ticket to destroy rights across the board.

Now we believe that the majority of teachers in America know our system must be reformed to put students first so that America can compete that teachers don't teach to become rich or famous. They teach because they love children.

While Free Choice Vouchers didn't fulfill my vision of a health care system in which every American would be empowered to hire and fire their insurance company they were a foothold for choice and competition and a safety valve for Americans whose employers are already forcing them to bear more and more of their family's health insurance costs.

The U.K. needs a system for family migration underpinned by three simple principles. One: that those who come here should do so on the basis of a genuine relationship. Two: that migrants should be able to pay their way. And three: that they are able to integrate into British society.

The last three decades have seen the collapse of the family wage system.

The Hispanic community understands the American Dream and have not forgotten what they were promised - that in the U.S. a free market system allows us all to succeed economically achieve stability and security for your family and leave your children better off than yourselves.

My friends and family are my support system. They tell me what I need to hear not what I want to hear and they are there for me in the good and bad times. Without them I have no idea where I would be and I know that their love for me is what's keeping my head above the water.

There are many countries where you can only believe more or you can believe less. But in the United States we have this incredible smorgasbord and it really interests me why people are drawn to one faith rather than another especially to a system of belief that to an outsider seems absurd or dangerous.

The facts of science are real enough and so are the techniques that scientists use and so are the technologies based on them. But the belief system that governs conventional scientific thinking is an act of faith.

I have faith in the justice system and what will happen will happen. I'm just trying to do the right thing.
