Yes, that is correct, and also to prop up their economies.

Australia is in per capita recession but bought in a shitload of immigrants which masks the overall numbers and avoids the headlines. Some added benefits for Gov:

- puts demand side pressure on housing which is basically the whole economy in these Ponzi states so it keeps house prices inflated

- puts supply side pressure on wages which they stupidly believe slows inflation but really just fucks the citizens even harder

- provides cheap labour for their friends in business

- can flood areas of the labour market where the people would traditionally support their political opponents

It’s definitely an element of long-term trying to prop up their tax base but a lot of short term cynical bullshit thrown in.
