What $1.2 Trillion Can Buy

The human mind isn't very well equipped to make sense of a figure like $1.2 trillion. We don't deal with a trillion of anything in our daily lives, and so when we come across such a big number, it is hard to distinguish it from any other big number. Millions, billions, a trillion — they all start to sound the same.

The way to come to grips with $1.2 trillion is to forget about the number itself and think instead about what you could buy with the money. When you do that, a trillion stops sounding anything like millions or billions.

For starters, $1.2 trillion would pay for an unprecedented public health campaign — a doubling of cancer research funding, treatment for every American whose diabetes or heart disease is now going unmanaged and a global immunization campaign to save millions of children's lives.

Combined, the cost of running those programs for a decade wouldn't use up even half our money pot. So we could then turn to poverty and education, starting with universal preschool for every 3- and 4-year-old child across the country. The city of New Orleans could also receive a huge increase in reconstruction funds.

The final big chunk of the money could go to national security. The recommendations of the 9/11 Commission that have not been put in place — better baggage and cargo screening, stronger measures against nuclear proliferation — could be enacted. Financing for the war in Afghanistan could be increased to beat back the Taliban's recent gains, and a peacekeeping force could put a stop to the genocide in Darfur.

All that would be one way to spend $1.2 trillion. Here would be another:

The war in Iraq.
