Ireland too iirc, as it became an Alex Jones talking point for a while that someone in Ireland said they needed 4 million immigrants to prevent similar issues. The person was just using that as a measure, and iirc it's quite a while in the past so not sure if it's the same today.

It's not as bad as what people who use the term 'flyover states' think.

It can still be greatly improved, and immigration is the way to do it.

Just drive through rural America and you'll see dead town after dead town. Mainstreets with less than 50% of their buildings occupied is the norm.

It doesn't have to be this way. On average, each additional person contributing to an economy bolsters it rather than detracts from it.

Stagnant economies, brain drain, lack of opportunity, drinking water contaminated with farm runoff and/or lead, crumbling infrastructure, and lack of funding for education and other government services.
