as efficiency and productivity increased, business found people weren't consuming more. so they had to restrict supply and raise prices. imagine: > make 1000 things for 1 > sell for 2 > earn 2000 improve > make 2000 things for 1 > sell for 2 > still only earn 2000 because people don't need more of what you make they're not going to lower their prices. so they will either make less or charge more.
