Six months to make a sandwich without trade

Stuff reports:

What do you get when you give a man six months and NZ$2400 (US$1500)? A single sandwich.

But it’s not just any sandwich, of course.

Andy George, host of YouTube series How To Make Everything, attempts to make everyday things from scratch, gathering and growing the raw ingredients before assembling the final product.

This is a good lesson about the value of trade.

Some people think trade is a zero sum game. Exports are good and imports are bad.

Trade is about relative value. You could spend six months of your time making a sandwich from scratch, or you can trade with other people who allow you to purchase a sandwich for $5 instead of $2,400.
