Nt all of that is good, and saying unions brought most of those is the worst possible kind of revisionist bullshit there is.
Yes at one point in the very distant past there was some real reason to have unions. But they are proof of the statement that "absolute power corrupts absolutely" and the usefulness they once had has vanished... I hold no grudge against existing unions, well the ones that have let the companies live anyway. To form new unions in this day and age is to strangle a company of entire sector of industry in the cradle.
