That's the opposite of corporatism. Corporatism would be if the corporations made demands of the government, and the government bent over backwards.

The US government has lots of corporatism, but this isn't an example of that.

There are always winners and losers in political discussions not every corporation could have control over decision making. But that doesn't mean companies aren't playing a major rool in decisions. I'd imagine companies owned by Larry Ellison (fox and soon cnn) have a much larger role in decision making and agenda setting that most people are comfortable with.

Corporatism/corporatocracy is about representative groups from industries being embedded in the state and their interests shaping state policy.

The current US administration's relationships with corporations is more seeking to maximise how much bribe money it can extract from them, whilst undermining them with counterproductive policies no matter how big the tax breaks are.
