Here's the secret.
The more citizens you have, the higher your national debt can go, the longer it takes before the debt bubble collapses.
They're trying to delay the inevitable for as long as possible.
>what exactly is this inevitability?
All those welfare programmes aren't paid for with taxes.
They're paid for with loans. Specifically, loans from 30 or more years ago when the babyboomers in office took them.
The younger generation is expected to pay the taxes today to pay for the loans of 30 years ago, but that debt repayment has already been reallocated to newer loans by the same babyboomers who are still in charge.
>so?
1 retiree requires about 4,5 adult 40-hour weekly worker to sustain the social pensions and other welfare schemes for the elderly.
They didn't get 5 children EACH. They got 1 each.
That means their spreadsheets genuinely do require immigration to boost the numbers.
But here are the two primary problems with that for the economy, the ponzi scheme and the ruse.
First, each immigrant is a net cost to the economy. They don't produce more wealth than they consume in benefits and subsidies, ironically the very thing the spreadsheet expects them to produce for others instead.
Second, each immigrant you bring in is another elderly retirement that requires 5 kids EACH to fund, and immigrants despite their Catholic proclivity for reproduction DO NOT HAVE 5 KIDS EACH.
Which means that ironically enough, mother of ironies, bringing more immigrants in to boost the system and prop it up (which boomers genuinely believe), is actually destroying it faster than ever before.
