I think most I know don't like people coming into their country breaking laws, particularly Immigration Laws.
Some people are upset. Some people are more upset than others.
Importing large amounts of people using the law to enable legal immigration, to malign, or aggravate a local culture in a country is probably a bad idea.
I can't think of something more politically charged than importing large numbers of people for the gain of a few, to undercut the hard work of a local culture to educate themselves only to find that they are priced out of the market. You can see this happening in the USA right now and it is creating structural problems economically that, are going to be quite explosive in the coming decade.
This idea that anything goes for profit or labor cost to obtain unfair trade deals by leveraging Third world people in a 1st world context will bring war if it isn't stopped. It incites people to listen to these globalist complain they can't find qualified people to do a given job, for example, when they are being blatently untruthful and only care about the cost of labor.
A very very nasty big war is coming.
