Economics is a social science, not a physical science.

Proving that profit is economically and morally justifiable, rather than the result of exploitation, has been a central preoccupation of neoclassical economists.

Growth can also involve producing services instead of goods. In particular, a major expansion of public and caring services (like child care, education, elder care, and other life-affirming programs) would generate huge increases in GDP and incomes, with virtually no impact on the environment.

Capitalism, in contrast, has existed for fewer than 300 years. If the entire history of Homo sapiens was a 24-hour day, then capitalism has existed for two minutes.

Never trust an economist with your job. Learn about economics yourself. And make up your own mind about what might protect your job - and what might destroy it.

Kalecki thus precisely predicted the economic and political U-turn that occurred with the advent of neoliberalism. Kalecki also argued that fundamental institutional changes, especially regarding wage-setting and other aspects of the employment relationship, would be essential if full employment was to be sustained.

This relationship is the foundation for the argument, made by some trade unionists and labour advocates, that high wages can actually be "good for business". The precedent set by Henry Ford in 1914, who offered workers $5.00 per day (a very high wage at the time) so they could afford to buy the same cars they made, is often invoked.
