@NathanpmYoung That's the best I came up with too. Anti immigration sentiment seems to be correlated to feelings of lack of control, and not actual immigration levels, so it's possible chaotic illegal immigration might through backlash reduce legal immigration enough to be net negative.
@NathanPmeung这也是我想到的最好的。反移民情绪似乎与缺乏控制的感觉有关，而不是与实际的移民水平有关，因此，混乱的非法移民可能会通过反弹减少合法移民，从而达到净负面效果。
