Hence, we cannot make everyone richer.

Sometimes we can, sometimes we can't. If there is a mismatch between demand and capacity, because nominal purchasing power is not adequately distributed, then printing money and giving it to the poor will make them richer, because the productive system can meet their demand without raising prices. Indeed, factories running at capacity can sell things more cheaply than factories running at less than full capacity.

Of course, "short-sighted" solutions of money-giving don't work; they're short-sighted. But what about well-thought-out money-giving solutions?

The pandemic relief is not being taxed by inflation. The "inflation" would have happened anyway, because the pandemic (and, perhaps, our trade policy) have disrupted the supply chain. This is not demand-pull inflation; it is supply shock inflation. There's a difference.

And yes, technology is taking jobs. Some technology increases performance. Trucks beat horses, and teamsters can become, well, teamsters. But some technology just does things more cheaply. Is the in-branch ATM really any faster than the nice lady at the window? No. It just costs less. These fine points matter.

As Euclid is said to have said to some King, there is no royal road to geometry. You can't learn "Economics in One Lesson." You have to have read enough other economists to know that Hazlitt was mostly wrong. Indeed, to say that we must not be stuck in the past and then cite Hazlitt is to ignore your own advice.
