You're missing the point. Let's say you have a country with a million middle class people (only). Over a ten year period a million poor people with a sixth grade education and no ability to speak the language immigrate to your country (legally, illegally, doesn't matter). If you look at the poverty statistics, you've had an enormous increase in poverty and your average wage is much lower. But that's just... math. Also, those people will push down wages on the lower end. Wages are a function of supply and demand. When you add a whole bunch of people to the supply without increasing demand, the clearing price will be lower just like the price of cars would drop if you doubled production and dumped them on the market. If you're a native born person you're not going to get a raise for a long, long time. If you really believe suicides are in part driven by income inequality, you can't pretend immigration isn't part of the problem.
