Most of it was Covid driven. When you pump an extra 6-7 trillion dollars into an economy there is going to be a massive spike in demand. This in turn increases demand for labor and politicians don’t give a shit about all of the downstream affects that will come later by allowing in too many legal or illegal immigrants. They just want the growth in the moment to tout how good the economy is doing.If anything, Springfield is a model in what not to do when it comes to expecting growth. The town attracted plenty of laborers, but didn't do anything to attract the doctors, teachers, police officers, etc., those new laborers would inevitably need. They saw all the potential $$$ coming in, but didn't give any thought to how many of those $$$ would need to be spent to make the change sustainable.
