There’s really only 2 things you need to know to predict GDP growth, and they’re also the limiting factors, and it works looking backwards as well. Population growth plus productivity growth = %increase in GDP. That’s how economists do it.
Population growth is easy to predict, it’s pretty slow at 0.9%. Productivity growth is harder to predict but employment is pretty high already and I don’t see any evidence of a ton of people re-entering the workforce.
If the economy can sustain low to middling 2% GDP growth then thats doing as well as it can.
Now, you CAN goose those numbers up temporarily with massive deficit spending like we’re doing now, but it will always revert back to what it should have been when the deficit spending stops, and after a correction going the opposite direction. It won’t be so great when the music stops.
