Your "logic" is dogshit.
Immigrants only decrease wages by 0.7% easily solved by government initiatives.
Non-sequitur argument - no explanation of how "government initiatives" increase wages for citizens
Increasing public sector builders and policies against land hording
Again, non-sequitur. Immigrants do not actually do anything against the house flipper market. In fact, it could be argued they make it worse by encouraging more houses to be rented out as cheap apartments meant for five families at once.
Closing diploma mills will stop 500,000 international students
Yes, this is the only point you are making that is good. We should have fewer international students coming over here. This is not an argument for immigration.
TL;DR you are dumb and your brain is shit like your skin.
