Obama supports zero-based budgeting?

Now, many of these plans will cost money, which is why I've laid out how I'll pay for every dime: by closing corporate loopholes and tax havens that don't help America grow.

But I will also go through the federal budget line by line, eliminating programs that no longer work and making the ones we do need work better and cost less, because we cannot meet 21st-century challenges with a 20th-century bureaucracy.

1. That no politician will end America's consumption of foreign oil. Ever.

2. That no politician will figure out a way to bring the bottom half of America's children up to the level where they can benefit from a college education.

3. That no politician will figure out a way to make American health care--meaning virtually unlimited access to specialists and technology--affordable for everyone.

4. That no politician will alter the trends in technology and family structure that are driving the distribution of income and wealth.

5. That no politician will produce a sustainable fiscal outlook without trimming future Social Security and Medicare benefits. (I might have ended the previous sentence simply by putting a period after "outlook")

6. That no politician needs to create jobs. There is always too much work to be done. The problem is never to create jobs. The problem is for individuals to adapt their abilities to ever-changing job opportunities.

7. That no politician will be able to articulate an economic difference between moving labor or goods from country X to country Y and moving labor or goods from Maryland to Virginia.
