On point #1, decline in Agri/GDP ratio means more agri jobs lost. Weird.
Even socialist Vietnam and China, more developed Thailand and Malaysia, have shrinking share of Agri/GDP ratio. It's the natural progression of societies. Overall productivity across countries keeps rising, thanks to scientific innovation and market competition. We will need less rural labor, other inputs, to feed an ever-rising population.
The same point re decline in manufacturing/GDP ratio, leading to more manufacturing jobs lost. Decline in ratio is not automatically bad as other sub-sectors in the industry sector, services sector, have absorbed excess labor from manufacturing as the latter uses more machines and robots.
On point #3, the number of poor people have increased. Well, the definition of "poor" is evolving. Until a few years ago, it was earning $1/day/person or less, now it's around $1.5/day/person. Before, the poor were riding cows or horses, now they ride motorcycles or buy 2nd/3rd-hand cars or jeeps. Before, the poor were using smoke signals to send a message, now they have fb and twitter on their cheap smart phones.
