Re: The idea behind mass immigration is that you have a constant supply of workers and tax payers to subsidize the welfare of the retiring natives of a country. Politicians run up deficits and then cover their boo boo via immigration. I'm not making a value judgement on immigration here, but politicians have a bad habit of sacrificing the future for current benefits largely because their political career is a relatively small slice of time. It's why we have debt and pension problems. True, voters play a part by having short memories, voting for instant gratification.
