This fundamental inequality, which I will write as r > g (where r stands for the average annual rate of return on capital, including profits, dividends, interest, rents, and other income from capital, expressed as a percentage of its total value, and g stands for the rate of growth of the economy, that is, the annual increase in income or output), will play a crucial role in this book. In a sense, it sums up the overall logic of my conclusions.The remaining part of the introduction lays out the structure of the book, and is basically an exposition of how he will evaluate the concepts briefly touched upon in the introduction.
The central thesis of this book is precisely that an apparently small gap between the return on capital and the rate of growth can in the long run have powerful and destabilizing effects on the structure and dynamics of social inequality. In a sense, everything follows from the laws of cumulative growth and cumulative returns, and that is why the reader will find it useful at this point to become familiar with these notions.Saying thus, Piketty in this chapter concentrates on what is meant by growth. The two aspects he considers are: demographic growth and economic growth.
To put it bluntly, the discipline of economics has yet to get over its childish passion for mathematics and for purely theoretical and often highly ideological speculation, at the expense of historical research and collaboration with the other social sciences. Economists are all too often preoccupied with petty mathematical problems of interest only to themselves. This obsession with mathematics is an easy way of acquiring the appearance of scientificity without having to answer the far more complex problems of the world we live in. There is one great advantage to being an academic economist in France: here, economists are not highly respected in the academic or intellectual world or by political and financial elites. Hence they must set aside their contempt for other disciplines and their absurd claim to greater scientific legitimacy, despite the fact that they know almost nothing about anything.
In any case, truly democratic debate cannot proceed without reliable statistics.
[E]conomists like simple stories, even when they are only approximately correct (218)
[T]he discipline of economics has yet to get over its childish passion for mathematics and for purely theoretical and often highly ideological speculation (32)
...particularly when one belongs to the upper centiles of the [wealth] distribution and tends to forget it, as is often the case with economists (267)
When we say that a distribution of wealth is a Pareto distribution, we have not really said anything at all. (368)
For far too long economists have sought to define themselves in terms of the supposedly scientific methods. In fact, those methods rely on an immoderate use of mathemetical models, which are frequently no more than an excuse for occupying the terrain and masking the vacuity of the content. (574)
Capital is never quiet: it is always risk-oriented and entrepreneurial, at least at its inception, yet it is always tends to transform itself into rents as it accumulates in large enough amounts - that is its vocation, its logical destination (115-6)
Thoughout most of human history, the inescapable fact is that the rate of return on capital was always at least 10 to 20 times greater than the rate of growth of output (and income). Indeed, this fact is to a large extent the very foundation of society itself (353)
[In the 1970s] [f]or the first time in history... wealth accumulated in the lifetime of the living constituted the majority of all wealth (402)
Private wealth rests on public poverty (567)
Once constituted, capital reproduces itself faster than output increases. The past devours the future. (571)
It may be excessive to accuse senior executives of having their "hands in the till", but the metaphor is probably more apt than Adam Smith's metaphor of the market's "invisible hand" (332).
In the United States the Supreme Court blocked several attempts to levy a federal income tax in the late nineteenth and early twentieth centuries and then blocked minimum wage legislation in the 1930s, while finding that slavery and, later, racial discrimination were perfectly compatible with basic Constitutional rights (653 n49)
The bipolar confrontations of the period 1917-1989 are now clearly behind us. The clash of communism and capitalism sterilized rather than stimulated research on capital and inequality by historians, economists, and even philosophers. It is long since time to move beyond these old controversies... (576)This isn't simply a left, liberal, or Marxist book, as some have charged. Perhaps it's a claim for a new politics based on data, an ideology for the world of 538.com.
[B]y 2100 the entire planet could look like Europe at the turn of the twentieth century, at last in terms of capital intensity. Obviously, this is just one possibility among others. (196)
The history of the past two centuries makes it highly unlikely that per capita output in the advanced countries will grow at a rate above 1.5% per year, but I am unable to predict whether the actual rate will be 0.5%, 1%, or 1.5% (95)
If the twenty-first century turns out to be a time of low (demographic and economic) growth and high return on capital (in a context of heightened international competition for capital resources), or at any rate in countries where these conditions hold true, inheritence will therefore probably again be as important as it was in the nineteenth century.
