Venture capitalist Nick Hanauer points out the obvious: Low wages create and sustain poverty, not lousy schools. Hanauer encapsulates conventional wisdom:

"Once upon a time, America created a public-education system that was the envy of the modern world. No nation produced more or better-educated high-school and college graduates, and thus the great American middle class was built. But then, sometime around the 1970s, America lost its way. We allowed our schools to crumble, and our test scores and graduation rates to fall. School systems that once churned out well-paid factory workers failed to keep pace with the rising educational demands of the new knowledge economy. As America's public-school systems foundered, so did the earning power of the American middle class. And as inequality increased, so did political polarization, cynicism, and anger, threatening to undermine American democracy itself."

For most of my adult life, I’ve railed against “corporate capitalism”, “consumer capitalism” and “crony capitalism”. It took me a long time to see that the problem is not the adjective, but the noun.

While some people have rejected capitalism gladly and swiftly, I’ve done so slowly and reluctantly. Part of the reason was that I could see no clear alternative: unlike some anti-capitalists, I have never been an enthusiast for state communism. I was also inhibited by its religious status. To say “capitalism is failing” in the 21st century is like saying “God is dead” in the 19th. It is secular blasphemy. It requires a degree of self-confidence I did not possess.

But as I’ve grown older, I’ve come to recognise two things. First, that it is the system, rather than any variant of the system, which drives us inexorably towards disaster. Second, that you do not have to produce a definitive alternative to say that capitalism is failing. The statement stands in its own right. But it also demands another, and different, effort to develop a new system.

Capitalism’s failures arise from two of its defining elements. The first is perpetual growth. Economic growth is the aggregate effect of the quest to accumulate capital and extract profit. Capitalism collapses without growth, yet perpetual growth on a finite planet leads inexorably to environmental calamity.

The modern world doesn’t look like this at all. All the files on a typical computer belong to a non-expert user (for simplicity I am ignoring shared devices — this doesn’t really undermine the argument as I hope you will see). Indeed, the whole computer typically belongs to a single user. Printers do not need accounting and similarly belong to the same user. The enemy is the software that is running on the machine. Users no longer have a good understanding of the software they run. Software is enormously complex and uses all sorts of resources, many distributed over multiple systems, to accomplish their tasks. And frequently their task is only superficially in service of the user.

In short, the old threat model was untrusted tenants, trusted software, unit of protection is files and devices. The new threat model is trusted tenants, untrusted software, unit of protection is individual data items.
