00:04:01.372 --> 00:04:03.665 What was causing wealth to move from being the exception 00:04:03.665 --> 00:04:05.382 to being the norm. 00:04:05.705 --> 00:04:07.319 Now we look around, and try to figure out 00:04:07.319 --> 00:04:10.598 what causes poverty instead of what causes prosperity. 00:04:11.540 --> 00:04:14.237 You are watching Everyday Economics, 00:04:14.237 --> 00:04:16.296 a course where we use the lens of Economics 00:04:16.296 --> 00:04:18.375 to explore everyday questions. 00:04:18.815 --> 00:04:20.437 This section is about trade. 00:04:21.023 --> 00:04:23.583 In the upcoming videos, we will attempt to explain 00:04:23.583 --> 00:04:26.244 how trade plays a role in our prosperity. 00:04:26.966 --> 00:04:29.173 You also get to decide where the course goes. 00:04:29.500 --> 00:04:31.436 Maybe you have some questions related to trade 00:04:31.436 --> 00:04:33.197 that you've wondered about. 00:04:33.197 --> 00:04:35.366 We'll cover the basics and then you tell us 00:04:35.366 --> 00:04:37.648 what topics come next. 00:04:37.648 --> 00:04:42.487 ♪ [music] ♪
