Loosely speaking it’s the same concept. The point is that the gains as the economy grows are nearly all going to the same small group of people.

That's the GOP plan, classic horse and sparrow economic policy (old name for "trickle down").

For those unfamiliar with "horse and sparrow", an admittedly rural metaphor:

Which makes sense, I suppose, as they are the ones who are responsible for the mechanization/automation that allowed productivity to continue to grow beyond the natural capability of humans alone. They decided to invest in that technology explicitly for the added gains it would bring them personally.

There was once a promise that schooling would provide the path to allow everyone to contribute their own automation to the economy, allowing everyone’s income to continue to increase with the productivity gains they created, but it hasn’t played out in practice. The burger flipper still flips burgers rather than focusing on developing a burger flipping machine.

It's not the same concept at all, it's an undue conflation of GDP growth, income and income inequality. (See my other reply)
