Using the word ALL or to say something is true every time is usually a questionable position. That said, in MOST cases big corporations will chew you up and spit you out. They are like Frankenstein monsters who will cheerfully kill you—literally—for an extra nickel in dividends.

Look at pharma companies, charging upwards of $1000/month for insulin which diabetics need every single day JUST TO STAY ALIVE. And that insulin costs only a few dollars to make. And the guy that first created insulin GAVE AWAY THE PATENT FOR FREE so that diabetics could get cheap insulin.

So, let's not get too supportive or forgiving of corporations. The cases where corporations behave nicely when it's more profitable to be brutal are few and far between.

Oh, and then there's Boeing. It's great for engineers who want to be pressured into skimping on safety.
