One of Katie Porter's friends in Congress:
Rep. AOC Exposes Price Gouging underlying 'Inflation' - YouTube in a Congressional hearing on April 6
AOC first mentioned people being squeezed by lower wages and higher prices. Then got into corporate consolidation.
Like four meat-processing companies accounting for 53% of all US meat processing. Cargill, JBS, Cargill, Tyson, Smithfield.
The four largest retailers have 35% of the market share. WalMart and Amazon are 2/3 of this or 1/4 of the total (WM 14%, Am 10%).
She then discussed the effects of oligopoly on markets: a big departure from the ideal of perfect competition.
Then about the effect of WalMart Supercenters on employment. One can find that out by comparing where they are approved to where they are not approved. Wages go down by 5.2%, employment by 2.9%, and participation by 1.4%.
Lack of competition is costly to workers, reducing their wages by 15% - 25%.
She sums up by noting that oligopoly of product making raises prices and oligopsony of employment lowers wages, squeezing many Americans in both directions.
She then notes that many of these industries do not exactly have optional participation: food, energy, transport, communication, retail.
Then an odd result: no correlation of wage inflation and price inflation by industry. One of the witnesses then noted that some industries, like pharmaceutical ones, car-rental ones, and large online companies like Google and Facebook for their advertising, don't take labor costs into account in their pricing.
AOC then mentioned 80% of soybean processes and 73% of beef processors being only four companies.
Then antitrust and labor unions. It's more difficult to organize labor unions in large companies like Amazon and Starbucks because of their union busting, and penalties are not strong enough. Mergers are an anti-union technique.
