Why do employees hire them? We can probably assume, on average, that they do not speak or read English as strongly, that they are less familiar with the businesses they work in, and that they are less familiar with the norms of Western customer service sector. The only thing in their collective favour, in the sort of jobs you name, is that they are more willing to work unsociable hours for low wages. If you force employers to compensate employees- well, I hesitate to say "fairly", because I'm a realist, but less unfairly, then the incentive to prefer immigrant workers is mostly going to dissipate.
These "left" arguments against immigration are framed as somehow workerist because they will inconvenience rich people, but they're always carefully posed in such a way as to refuse the authority of the public over rich people. We can take any measure to frustrate the attempts of the rich to exploit the poor, they seem to concede, as long as we don't challenge their fundamental right to exploit the poor.
It's because they will work for rates New Zealanders won't and they can be ignorant of labour laws. There's been several cases of labour exploitation here including a conviction for slavery our first one. Person responsible was also a migrants
who was exploiting their own people. Some have also been busted paying less than half minimum wage.
Another employer who was paying slightly above minimum wage was complaining about a lack of workers and saying young NZers had a lack of work ethics. Was paying 18 dollars an hour in Queenstown. Queenstown costs around $500 a week for a room and in hospitality you might not get a 40 hour week. In the 90s we used to go to Central Otago for work it's not worth it now.
In Auckland McDonalds pays around $20 an hour, average house price 1 million dollars.
Once again in the 90s you could get a house for around $60k. In Auckland less than $200 k. As I said per capita our migration rate hit 6 or 7 million per year (USA) or the Syrian refugee thing every year if you are German.
Here it was the right that did it, difference was open borders for the rich.
What are house prices like in London and can the locals afford to buy there on 25% less than the average wage? Can't blame climate change yet, it's the polititians for that one. Here they blame the National party, UK the EU, USA Mexicans. Trump's wall is idiotic as it won't work anyway, and walls don't really stop anyone either.
Economic distress same reasons that fueled the right in the 30s. You have to fix that first before people care about global warming or any other cause of the week sjw types latch onto. Right now it can suck a lot of you're poor, people won't care about something in 100 years time.
Our government just delivered a well being budget. It's a start and what they campaigned on but they couldn't push through tax reform as they lacked the numbers. Can't achieve anything if you're out of power though.
