When government has laws that require the use of resources in order to be enforced, and if the government does not have those resources, which must be given to it by the people, then the government's obligation to enforce it's laws pragmatically ends, depending on the circumstances. We have people who do not want to give government resources to do it's job, and then want to hold it accountable when it fails? That is a set up to fail.
Of course, on the immigration issue, you have another problem: the high number of people that feel it is morally wrong to enforce some of the laws at certain times. Those laws aren't exactly fair, and writing them to be fair is nearly impossible, and so we end up with the mess we have: legislators that pass laws that sound like solutions, but aren't, but that make voters happy.
And don't go run that up onto the Democrats. I've seen the Republicans do it just as often. It's called politics, and both liberals and conversations are guilty of it.
