People are reasonably good at estimating how things add up, but for compounding, which involved repeated multiplication, we fail to appreciate how quickly things grow.

An economy can survive with 10% of the population insolation. It can't survive when 50% of the population is in isolation.
Interpretation
High levels of isolation in a population can lead to economic collapse.
Paul Romer's quote emphasizes the importance of social interaction and connectivity for a thriving economy. While a small percentage of the population can be isolated without severe consequences, widespread isolation—when it affects a significant portion of the population—can severely disrupt economic stability and growth.
In practice
During a speech about the impact of social distancing on the economy, one could use this quote to highlight the risks of isolation.

When somebody discovers something like the quadratic formula or the Pythagorean theorem, the convention in science is that he can't control that idea. He has to give it away. He publishes it. What's rewarded in science is dissemination of ideas.
One of the most powerful insights in economics is this idea of a division of labor. You do the thing you're good at. Other people do something else that they're good at. The net effect is better for everybody.
Human material existence is limited by ideas, not stuff, people don't need copper wires they need ways to communicate, oil was a contaminant, then it became a fuel
It is the job of government to prevent a tragedy of the commons. That includes the commons of shared values and norms on which democracy depends.
In the developing world, most people don't yet live in big well-run cities. Given the chance to move to one, hundreds of millions of people would go there to get a job, get an education for their children, and live in a place that is clean, safe, and healthy.
The reason we should do a carbon tax is because it's the right thing to do. It's economics 101, elementary stuff.
One of the market's virtues, and the reason it enables so much peaceful interaction and cooperation among such a great variety of peoples, is that it demands of its participants only that they observe a relatively few basic principles, among them honesty, the sanctity of contracts, and respect for private property.
The market is incredibly inefficient and capable on rare occasions of being utterly dysfunctional. And people have a really hard time getting their brain around that fact. They want to believe that it's approximately efficient almost all the time, and it simply isn't true.
One of the arguments I make for the failure of the euro is that, at the time it was being constructed, there was a 'neo-liberal' ideology which said that all we need to do to make this thing work is to get deficits low, keep inflation low, and take down barriers, and then everything would be fine.
We've used up a lot of bullets. And we talk about stimulus. But the truth is, we're running a federal deficit that's 9 percent of GDP. That is stimulative as all get out. It's more stimulative than any policy we've followed since World War II.
Eviction is part of a business model at the bottom of the market.
