Do the math, 5 kids, $7,000 in child tax benefits, which is essentially free cash, independent of any other government benefits.  So they're making $35,000/yr in this tax free benefit alone.  Add in welfare and housing support that's another $25,000/yr plus free education (not if you're a taxpayer), free medical and subsidized housing.

So you make nothing, you've contributed nothing, you get close to $60,000/yr.  To make that amount working in Canada after tax, you need to pull in $120,000/yr, paying close to half your income in taxes and fees.  

It's a bit galling to see Trudeau giving them Canadian citizenship while viewing working Canadians with disgust and suspicion.  

We'll he's importing voters at taxpayer expense, which is why he extended voting rights to all refugees and treats them with kid gloves while scolding Canadian citizens for not doing enough.

What a traitor.
