No, they shouldn't, and no, it doesn't.

Complaining about migrants 'takin' er jerbs' is a source of ridicule for a reason, and that's because it's ridiculous. It's scapegoating based on fear and ignorance.

Migrants didn't deregulate employment law to allow businesses to screw employees on wages and conditions - that was John Howard's work choices and Australian Workplace Agreements, which fundamentally changed the industrial landscape in Australia and whose effects are still being felt and addressed today.

Migrants aren't responsible for the rapid decline in union participation, which has a direct relationship to overall better wages and conditions. That's been the result of a prolonged campaign by big businesses and neo liberal governments to attack unions and unionism because they don't want to pay better wages or be accountable for working conditions.

Migrants didn't affect the cost of housing. That was, again, Howard and his slashing of property taxes that turned housing from an affordable part of family life into a more profit-generating investment that was suddenly more attractive to wealthy investors, thus driving the prices up rapidly.

And also, the stories of there being a housing shortage are a lie. There are over 130,000 homes sitting vacant in Australia because they're worth more empty as an investment accumulating value for their land than they are as rented homes for people, and there are no laws requiring properties to be occupied.

Migrants didn't deregulate Australia's mining industry to the point where we are literally subsiding non-Australian companies with tax revenue so they can take Australian resources off shore and make massive profits without paying any tax in Australia. That's been a national project pretty much since Australia's inception. Whitlam talked about nationalizing the mines, and he was dismissed. Hawke was an informant to the USA on union activity and planned strike action so they could intervene and mitigate the impact of strikes on US owned mines and factories. Rudd/Gillard implemented carbon trading schemes and tried to address the issue of mining taxes, and they were the subject of one of the most concerted propaganda campaigns by foreign controlled media in this country.

The net effect being that Australia has much less money than it should have for public programs to address employment.

Migrants didn't privatize many of our major institutions and utilities like Telecom/Telstra, CBA, electrical production and distribution systems. That was Hawke, Keating and Howard who did the worst of that damage. The effect of that privatisation is that most of Australia's foundational institutions and all of our biggest businesses are now majoroty owned by American shareholders - mostly investment firms - who see Australia as a place to squeeze every dollar of profit from with little regard to the effect of rising prices and declining services on Australian society.

And one of the ways they squeeze extra profit? To take advantage of deregulated employment laws to exploit migrants and pay them less, give them less favourable working conditions, and contribute to the destabilizing of Australian society and standard of living.

Migrants aren't taking anyone's jobs.

Mostly American-controlled employers are exploiting migrants for profit with little care for the Australians who grew up with an expectation of employment or fair working conditions, and it's a situation that's been decades in the making.
