We know multi national companies are bastards, no argument. They manipulate and defraud for profit. The cigarette industry knew in the late 1930s that cigarettes caused cancer. How many died bringing that to public notice? We know all engines can run on ethanol but the oil barons needed a market to sell their oil into so they ran a scare mongering campaign in the 1920s. Ceramic engines were invented in the 1950s and Ford bought the patent and shelved it because spare parts was too big a market and ceramic engines didn’t break down so often.
Today every house should have solar panels n them but you can’t tax them so governments went for wind farms that feed an existing power station which can be taxed.
Plenty of real conspiracies out there.
