Government policy makers, once enamored of fast-growing tech firms for their ability to boost GDP figures, have come to recognize the high cost of runaway growth. While such companies do increase in size, the real economies in which they operate are being drained rather than nourished. Lawmakers are starting to realize that authors and publishers shouldn't be made poorer by Amazon; cab companies shouldn't be made less profitable by Uber; and the people of San Francisco shouldn't be priced out of their homes by Google's inflationary presence. In New York, new regulations have been imposed that prevent an app like Airbnb from altering the fabric of a community by turning the city's apartments into flophouses.
