Well let's take a look. Let's take a look at the Great Depression.

Country A, in 1990, had about 300 per capita GDP as compared with Country B, which had 460 in per capita GDP.

And then this cancels with that and we get our real GDP.

Now we could compute something related to this,

It turns out even during the Cultural Revolution,

Just to show you what we plotted, here is income, GDP

Let's look at some data.

by stealing the future, selling it in the present and calling it GDP.

So if our engine's broken, guess what?

Let's say this is everything, this is the U.S. output.

In science, we do experiments systematically.

It is trillions, it's not billions.

We know the deflator is, can we figure out the real GDP in 2011 and that will be the real GDP in 2010 dollars, when we have the deflator relative to 2010.

But if attempted to that the generall level of prices has gone up by 2.5 , when form 100 to 102.5.

East Europe, Latin America, and OECD.

The incidence of malaria is about a couple of million people get infected every year.

That's just make a lot of sense to me.

And what people are beginning to ask is

People are thinking about the following questions

In the late 50s,

Cheap meaning sort of the cost of the military, not the cost of medical care.

So, you could have a GDP for a month you could have a GDP for a quarter of a year or you can be three months or you could have the GDP in a given year.

Let's extend it to a more complex economy to the world we live in and with that I want to look at the more formal definition for

I end now with the world. There, the Internet is coming.

It was the hardest hit of any country in the world.

We look upon it as a possibility of percentile increase.

It's basically two ratios of per capita GDP, per capita gross domestic product, so average income.

If I start a lawn mowing business and I go mow other people's lawns, or maybe before my wife I were dating, she used me to pay me to mow my lawns, then it would be included in GDP but maybe once we get married I just mow her lawn out of..because it's my lawn..we're the same family now..then it will not be included in GDP.

So you'd say fifty dollars minus the twenty dollars.

Now, of course, this cancels with that, that why we have multiplay both sides by the real,

I showed you that at 60 , to match that of Japanese males at 80 , this is the potential upside to GDP

What if the year were to end right over here?

So, to be fair and to alter our perspective, we have to bring in another data set, and that data set is GDP, or the country's earnings.

The size of the blob in this graph represents the size of the population, and the level of the graph represents GDP per capita.

Even at that rate, by 2100 average GDP per capita in the world will be 200,000.

That's not U.S. GDP per capita, which will be over a million, but world GDP per capita 200,000.

Here you have child mortality that is, survival four kids dying there, 200 dying there.

These are the blue bars.

By the way, Africa is very large.

What is the average difference here?

I would set this at 1 and I would call this 1.205, because then you wouldn't had all this sillines multiplaing and dividing by 100.

And so you have this 15 trillions divided by 1.025 or you can divide both sides by 1.025 and multiply both sides by the real GDP.

Here's how all of this impacts the big picture.

They paid 100,000 for it.

They have home brewed infrastructure and vibrant urban life.
