From the Economist(!)
Everyone needs enough to live on. Many of those who drop out of the job market, or who work in the gig economy, struggle to get by. And too often, help for the poor comes in ways that are cruel, inefficient, paternalistic or complex..
There is greater concentration even in non-tradable industries such as housebuilding—in which nobody thinks the quality of output is high.. There is evidence that leading firms, and not laggards, are behind the slowdown. In some industries they may feel they do not need to invest to keep ahead. The tech giants do innovate, but their ideas do not seem to spread through the economy.
