We live in a world where the Quantity of labor is growing much faster than the Quantity of capital. As the global labor market becomes more efficient and more competitive wages will decline and Labors share of income from production will decline drastically.
In a perfectly competitive labor market people earn only enough to work. 2 meals a day and a corrugated aluminum shack. The only way to achieve a better standard of living would be to own substantial amounts of capital.
