5 Companies own 80% of all stock in S&P 500 listed companies
Monopolies: The Death Knell Of Capitalism – it’s described here
They demonstrate the central role played by monopoly finance capital in economic life: ‘the Big 5 institutional investors – Blackrock, Vanguard, State Street, Fidelity, and JP Morgan – now own 80% of all stock in S&P 500 listed companies’; and they argue that this situation is mirrored internationally. They give examples of monopolies dividing up the world market .
for those that don’t get how this makes sense:
How many stocks you have in the market can be compared to a percentage out of a 100 on the market.
The more stocks you own, the more can be measured and added onto a percentage in comparison to the markets 100% value of potentially owning.
In this case, 5 companies control 80% of the market.
Tepper and Hearn have a thesis. Capitalism is defined by competition. The modern US economy, however, is dominated by monopolies. Therefore, US Americans live under ‘fake’ capitalism, a ‘grotesque deformed version of capitalism’ which is ‘as far away from the real thing as Disney’s Pirates of the Caribbean are from real pirates’ (p.xv). Tepper and Hearn have clearly identified one of the central issues in understanding modern capitalism: monopoly. In doing so, they have collected a wealth of useful material. Socialists should read this book, which is written in a very readable and enjoyable style, and use the information in it, but reject the reactionary politics that underlie it.
The book starts by analysing the extent of concentration in many US industries. Compiling evidence from various sources, the authors discover that four corporations control 90% of American beer; four airlines completely dominate airline traffic, often enjoying complete local monopolies in their regional ‘hubs’; five banks control half of US banking assets; in many states, the top two insurance companies have 80-90% market share between them; 75% of US households can only access one monopoly provider for high-speed internet; four companies control the entire US beef market and have ‘divided up the country’; three companies control both 70% of the global pesticide market and 80% of the US corn-seed market; Google’s share of internet search traffic is 90%; and so on.
As smaller competitors have been swallowed up by monopolies, over half of public firms have disappeared over the last 20 years: ‘On this trend, by 2070 we will only have one company per industry.’ ‘The scale of mergers is so extreme,’ Tepper and Hearn write, ‘that you would almost think American capitalists were trying to prove Karl Marx right’ (p.9).
