There are different ideas about what can spur economic growth, but you can have wage-led growth. If you're investing in workers and paying them a good wage, they spend that money in their local economies. Those jobs become more productive because the workers are paid better, so they're able to perform better.
An example of this is the four-day workweek trials that have been performed. Workers have been paid the same amount for fewer hours and have become more productive.
There's a real path to a more productive economy in which workers get a fair share of the value of what they're producing and are more invested in that and share it more in their local economies.
