OK look into the data average kerosene prices dropped from before and after standard oil, the predatory pricing arguments been fairly picked apart the last i checked. The antitrust was about unfair competitioncpractices, which could be argued has some economic benefits but also no reason that market changes couldn't have put pressure on it either.
I am not saying there is no role for government. But you're naive to believe that a political process of good and service production will be more efficient or less corrupt.
You've also ignored all the good markets create. You can only care about the environment or labor wages cause you're rich enough. Starving farmers living under Mao and stalin do not have that luxury.
And yes its real socialism, every planned economy hits the same information and humans not scaling problem.
