We consider that a villager living from subsistence farming and therefore having almost no use for money to be part of the very poor, less than 1$/day crowd.
Take this same peasant and send it working for some multinational company harvesting cocoa or sugar cane, under horrible, exploitative conditions for 2$ a day, and bam! poverty has been halved!
Ditto if you send him and his family in some shanty town collecting plastic on a rubbish pile, feeding on refuse : he's now making 3$ a day, poverty decreased again!
What is called "lifting out of poverty" is actually "making them a cog of a worldwide, money-based economy". That's a mixed blessing, to say the least.
