The idea that life gets better over time is very new, as it coincides with the Industrial Revolution. Before then, people thought in terms of food fuel and muscular mechanics. Same principle applied for slaves, livestock, and so on. After industrialization, people began to think in terms of (typically) chemical fuels and technical mechanics. Problems that would be solved by the introduction of slaves or domesticated animals were instead solved by the use of machines. Nowadays, in the Information Age, problems are not solved by throwing money or machines at it, but by utilizing the right information. The tools we make, make us.
