why are western countries being flooded by immigrants and refugees , and why do we continue to take them?

[Westerner]

Australia, for example is a target for the illegal immigrant, many thousands of muslims from Afghanistan, Iran, Lebanon, Iraq flood our country. yet to get here they bypass many muslim countries are they genuine refugees, many have been proven to be economic refugees.
why do they bypass countries more in keeping with their own religion and beliefs. one only has to look at Britain to see the folly of accepting them in their thousands.
do they really want our way of life, or is it closer to the truth that they want our social welfare system, the dole, and government handouts are much more than in the countries they bypass. eg. indonesia
they do not integrate, establish ghettos, and are happy to continue their hatreds, cults, and harsh religion. and we are supposed to welcome them with open arms
