I've seen my wife and her kids go through the immigration process and it's not fun at all. There are some very screwy and unneeded steps in it, and it could be modernized in my view, particularly with the quotas. But like Social Security, no politician will touch it beyond mouthing platitudes because "the other side" will demonize any proposal made. SS has a number of simple fixes, but no one can touch it. A lot of issues do, so politicians just ignore it beyond platitudes.
It reminds me of climate change though there they can at least throw money at it randomly and pretend.
