Macro level folks. The more you consume the more you produce. You produce more because of greed. You produce more because you can sell it.
Oh I got you. You mean as a society. Yeah, you gotta produce all that stuff to consume.
Dunno, we also have a mastery of hydraulics now as a substitute.
It's not a blank philosophical question either. This is the basic philosophical dilemma between capitalism (the rich man can have what he can afford regardless of what the poor man has) or communism (we all get the same no matter what). There is no option where you don't have to take something from someone if your goal is to make things fair.
In Sweden if a man fathers a child he can get a year off with pay and his job will be there when he gets back. He also does not need to take the year when the child is born but can take it when the child is a bit older. Obviously the Swedish state pays but they feel it benefits their society and makes for a healthier happier population.
But we were talking about fairness. How is this fair to the person who has no children? Or worse yet, the one who can't? He or she has to pay extra in taxes to subsidize years off for their neighbor who has 6.
In the Uk, there were many hydraulic power systems. steam engines raised water to tanks on top of towers, and pipes ran to various factories in the area to power the machinery. Here's just one example http://www.whatsinwapping.co.uk/wapping-hydraulic-power-station/
