Thomas Piketty and Inequality

I haven’t read this book, but judging from the blog reviews, it seems that is central point is that if the return on capital is higher than economic growth, then the owners of capital should become richer over time.

However, it seems that there are certain problems with this thesis. Firstly, an economy has an optimal capital stock, and thus can carry only a finite amount of wealth into the future. Attempts to save beyond this simply drive the return on capital negative. In the long run then, the capital stock approaches the optimal, and the return on savings should approach zero. Given the epic lack of capital in EM, we are still some 50-100 years from that, at least. On the other hand, we can comfort ourselves with the thought that even if Piketty is correct now, he won’t be correct forever.

If we think that the inequality in capital ownership is a problem, there is a simple solution. Simply have world governments buy up large quantities of the capital stock, say half of the stock and bond markets over a few decades. By reducing the supply of capital, savers, and by extension the wealthy, would have to compete for a smaller and smaller share of the optimal capital stock.

In the short term, this will drive up the price, but in the long run it limits the supply of available savings vehicles, and exposes the wealthy to inflation by giving them the choice between holding cash, or buying capital at such prices that returns are bound to be negative.

Of course, it seems that this would not be a politically acceptable move. For one thing, people seem to believe in the divine right of savers to reasonable returns. Of course, no one seems to equate the very wealthy with `hard working’ savers, but economically they are largely identical. To make it politically acceptable, the government would have to provide bonds at a reasonable rate of return. This could be managed, simply start selling bonds directly to savers at some limit such that no one person can own more than, say $500,000.  This is not very different from the UK’s pensioner bonds.

Driving down inequality by having the government buy up the capital stock. Its just the modern repackaging of Marxist ideas, but the difference is that we could do it now, without the terrible side effects. Just buy ETF’s and the government can be a silent partner in the world’s stock and bond markets. No interference in workings of capitalism, just lots more capital.
