Almost as an aside, the report indicated how adept Amazon, with a stock market value of nearly $900 billion, is at getting funding from California and local communities. This included $25 million from the California Film Commission to subsidize six productions, including the third season of “Sneaky Pete,” an Amazon crime drama, and $1.2 million from the California Office of Business and Economic Development toward an office building in Irvine for programmers.

The report noted on its title page that it was underwritten by the Los Angeles County Federation of Labor, which represents more than 800,000 members of 300 unions. The Economic Roundtable said that did not affect the results.

Among the report’s suggestions: that Amazon raise its minimum wage to $20 an hour, that it require its logistics subcontractors to do the same, that it provide child care at its warehouses and that it build affordable housing in its logistics communities.

The report draws on California Public Records Act requests filed with communities with Amazon facilities. Many of them nevertheless came up empty. The report noted that very little of Amazon’s business was known to anyone but Amazon. Communities are in the dark.

“Our conclusion is that it’s time for Amazon to come of age and pay its own way,” said Daniel Flaming, a co-author of the report. “This means paying its full costs to the communities that host it and the workers who create its profits.”
