People act like jobs are a non-renewable resource that, once filled, that’s all you get. This is a total misunderstanding of how consumer based economies work. Economic activity is demand driven. More consumers = more demand = more jobs. This is obvious if you think about it. It’s why cities can exist rather than collapse once hitting a certain population because all the jobs are taken and no one can work anymore. It’s why you find way more opportunities in cities rather than podunk rural villages.

Where the trouble comes in is that the population growth and job opportunities growth doesn’t necessarily happen at exactly the same rate at exactly the same time. There can be pain in the transitional period between when the population growth happens, and when the new demand stimulates the new job opportunities. That isn’t a reason to try and stifle the population growth. It’s a political issue. Something like universal basic services (or UBI), or a universal jobs guarantee where the government puts people to work on infrastructure projects (social housing in particular seems like a good idea) or the like, like New Deal era USA did until they can find something more to their liking would do a lot to soothe that pain.

Ultimately, the new economic activity that’s created from the growth is a good thing and ought to be embraced.
