WEBVTT 00:00:08.860 --> 00:00:11.320 00:00:11.320 --> 00:00:15.129 The astonishing growth in prosperity in the last two or three hundred years 00:00:15.129 --> 00:00:19.150 is one of the greatest events of humankind. Take the average human in say 00:00:19.150 --> 00:00:23.640 the year 1000 BC. He's poor, fighting to find food 00:00:23.640 --> 00:00:28.300 and to fend off diseases. Fast forward 500 years to the time of classical Greece. 00:00:28.300 --> 00:00:32.839 Still poor still hungry. How about another thousand years after that? 00:00:32.839 --> 00:00:36.329 It's the dark ages. Wow. Still poor. 00:00:36.329 --> 00:00:43.329 Then jump to the 18th century and forward. Things change rapidly. 00:00:43.390 --> 00:00:48.570 This phenomenon is known as the hockey stick of human prosperity. Take what is 00:00:48.570 --> 00:00:51.500 surely one of the most important measures human well-being: 00:00:51.500 --> 00:00:56.010 life expectancy. Before the Industrial Revolution 00:00:56.010 --> 00:00:59.570 life expectancy was around thirty years. Today 00:00:59.570 --> 00:01:02.719 in the United States we expect to live to be about eighty. 00:01:02.719 --> 00:01:06.170 Prior to the industrial revolution one 00:01:06.170 --> 00:01:09.350 in four kids would die before the age of 5. 00:01:09.350 --> 00:01:13.990 Today in developed countries it is more like one and two hundred. 00:01:13.990 --> 00:01:17.600 Due to better nutrition we grow to be four inches taller 00:01:17.600 --> 00:01:20.630 than we were just two hundred fifty years ago. 00:01:20.630 --> 00:01:24.429 Remember this disease? No you don't, because it was eradicated in 00:01:24.429 --> 00:01:28.950 1977. Look around--you'll find a roof over your head 00:01:28.950 --> 00:01:33.470 and a hard floor under your feet. Most of our ancestors with the huts with dirt 00:01:33.470 --> 00:01:35.119 floors and thatched roofs. 00:01:35.119 --> 00:01:38.209 Everything was infested with insects and rodents. 00:01:38.209 --> 00:01:42.179 Streets and alleys were open sewers. There were none of these. 00:01:42.179 --> 00:01:45.709 The filt was horrible and often toxic 00:01:45.709 --> 00:01:49.950 Our ancestors ate gruel and wore the same home-made underwear 00:01:49.950 --> 00:01:54.520 over and over. Now even the least fortunate Americans 00:01:54.520 --> 00:01:57.899 typically have electricity running water toilets 00:01:57.899 --> 00:02:01.200 refrigerators televisions and yes cheap 00:02:01.200 --> 00:02:06.119 washable underwear. Those of us who live in modern industrial society 00:02:06.119 --> 00:02:09.949 are incredibly, amazingly, off the charts rich 00:02:09.949 --> 00:02:14.349 compared to our ancestors and here's yet another huge difference between us 00:02:14.349 --> 00:02:18.370 and our ancestors. Before the Industrial Revolution 00:02:18.370 --> 00:02:22.099 people knew how to make from scratch many other things they consumed. 00:02:22.099 --> 00:02:25.370 They made a lot of their own clothing grew most to their own food 00:02:25.370 --> 00:02:28.420 and build their own dwellings. 00:02:28.420 --> 00:02:31.160 Fast forward to today and believe it or not 00:02:31.160 --> 00:02:35.450 none of us is a hint how to make the majority of the things that we consume. 00:02:35.450 --> 00:02:39.620 Just getting ready in the morning involves taking many trips around the 00:02:39.620 --> 00:02:40.430 globe. 00:02:40.430 --> 00:02:44.840 Take this coffee for example beans come from 00:02:44.840 --> 00:02:48.670 Guatemala and they were brewed in this coffeemaker from Switzerland. 00:02:48.670 --> 00:02:52.260 The container ship that carried the beans was built in Korea. 00:02:52.260 --> 00:02:56.459 It's insured by a company from London and it's captained by Frenchman 00:02:56.459 --> 00:03:00.019 who loves Turkish cigarettes. We've transitioned 00:03:00.019 --> 00:03:03.430 from each of us doing many things to each of us doing one thing. 00:03:03.430 --> 00:03:07.540 Having a job only makes sense in a modern world 00:03:07.540 --> 00:03:11.360 where each individual typically does only one type of work. 00:03:11.360 --> 00:03:14.860 So while we mostly only produce one thing 00:03:14.860 --> 00:03:19.260 doing one job each of us now consumes a whole bunch of products 00:03:19.260 --> 00:03:23.580 that require a whole bunch of jobs to produce. 00:03:23.580 --> 00:03:27.040 The question where prosperity comes from launched the field of economics. 00:03:27.040 --> 00:03:30.590 It's why Adam Smith wrote the first book in modern economics. 00:03:30.590 --> 00:03:34.840 An inquiry into the nature and causes of The Wealth of Nations. 00:03:34.840 --> 00:03:38.160 Back in 1776 when he published it 00:03:38.160 --> 00:03:41.690 Smith was trying to understand the causes of modern prosperity that were 00:03:41.690 --> 00:03:42.890 just starting to appear. 00:03:42.890 --> 00:03:46.940 Poverty and starvation were still normal as they had been from the beginning 00:03:46.940 --> 00:03:50.170 but in the late 18th century for the first time ever 00:03:50.170 --> 00:03:53.450 the masses began to enjoy riches once reserved 00:03:53.450 --> 00:03:57.820 only for the nobility. It is this mass prosperity that Adam Smith 00:03:57.820 --> 00:04:02.810 sought to explain. Why was it happening? What was causing wealth to move from being 00:04:02.810 --> 00:04:03.720 the exception 00:04:03.720 --> 00:04:08.109 to being the norm. Now look around try to figure out what causes poverty 00:04:08.109 --> 00:04:12.390 instead of what causes prosperity. You are watching 00:04:12.390 --> 00:04:16.079 Everyday Economics, a course where we use the lens of Economics 00:04:16.079 --> 00:04:19.620 to explore everyday questions. This section is about 00:04:19.620 --> 00:04:24.289 trade. In the upcoming videos we will attempt to explain how trade 00:04:24.289 --> 00:04:29.110 plays a role in our prosperity. You also get to decide where the course goes. 00:04:29.110 --> 00:04:32.510 Maybe you have some questions related to trade that you've wondered about. 00:04:32.510 --> 00:04:39.510 We'll cover the basics and then you tell us what topics come next. 00:04:46.790 --> 00:04:47.040
