It's hard to argue how illegal immigrants who are often abused and confined to bad, irregular jobs (and sometimes turn to criminals due to these conditions) would improve the culture. There are better cultures and worse ones (such as, prison culture or Khmer Rouge), and we're talking about degradation here. With educated immigrants, the story may be different. But it's not the kind that most people worry about.
