When it comes to work, I think that overpopulation is a problem which immigration adds to... I'm amazed to hear what changes were made for workers in the past when the plague killed huge numbers of people. They had quite the chance to get better conditions for themselves. If you can easily be replaced then you become less valuable and feel it. Everything is temporary and unstable now... this is the reality we live now. From temporary jobs we yo-yo between rather than upwards in mobility, renting and moving a lot, being long distance from family, etc.
