Could BS jobs save the economy from an AI driven collapse of wages?

The concept and book by David Graeber an anthropologist who studied and wrote about BS jobs. Found that around 40% of modern jobs could be classed as BS jobs as they added nothing to the production or deliver of goods or services. It's amazing that a market driven economic system would allow such a high percentage of jobs to have so little impact to the productivity or profitability of a company. But if you zoom out a bit further than the companies profit margin, there are other factors in play e.g. a manager who manages a larger team is a better manager.
