No it was not, but then neither was Carnegie, Rockefeller, Mellon, Pullman, etc. They bought and sold the government, the army, the cops to suit their own bottom line at everyone else's expense.
That would be the socialist agitprop version of history. What they did was build this nation's industrial base. If you want to see what this country would be like without them, go look south of the Rio Grande. Every time Rockefeller bought someone out, he offered them a darn good price, and gave them the option of taking it in cash or Standard Oil stock. Those who the leftists claim he destroyed were the ones who took cash.
If he bought the government, then why did they break up his company?
We need to protect ourselves from the government and we need the government to protect us from big business,
No, we need to make wise, well informed choices, and that is how we protect OURSELVES from big business, which, unlike government, cannot coerce us.
Businesses don't prosper if they ruin their customers.
