“How do wealth-income and capital-output ratios evolve in the long run, and why? Until recently it was difficult to properly address this question, for one simple reason: national accounts were mostly about ﬂows, not stocks. Economists had at their disposal a large body of historical series on ﬂows of output, income and consumption – but limited data on stocks of assets and liabilities. When needed, for example for growth accounting exercises, estimates of capital stocks were typically obtained by cumulating past ﬂows of saving and investment. This is ﬁne for some purposes, but severely limits the set of questions one can ask.”

“I can now present the first fundamental law of capitalism, which links the capital stock to the flow of income from capital. The capital/income ratio β is related in a simple way to the share of income from capital in national income, denoted α. The formula is
α = r × β
Where r is the rate of return on capital.
For example, if β=600% and r = 5%, then α = r × β = 30%.
In other words, if national wealth represents the equivalent of six years of national income, and the rate of return on capital is 5 percent per year, then capital’s share in national income is 30 percent.”

“The essential measure of the success of the economy is not production and consumption at all, but the nature, extent, quality, and complexity of the total capital stock, including in this the state of the human bodies and minds included in the system. In the spaceman economy, what we are primarily concerned with is stock maintenance, and any technological change which results in the maintenance of a given total stock with a lessened throughput (that is, less production and consumption) is clearly a gain. This idea that both production and consumption are bad things rather than good things is very strange to economists, who have been obsessed with tile income-flow concepts to the exclusion, almost, of capital-stock concepts.”

“When the rate of return on capital exceeds the rate of growth of output and income, as it did in the nineteenth century and seems quite likely to do again in the twenty-first, capitalism automatically generates arbitrary and unsustainable inequalities that radically undermine the meritocratic values on which democratic societies are based.”
