Immigration as a solution to population decline is absolutely outsourcing and pretty much cultural suicide.
There are a lot of naive answers to this thread... Do people not realise that countries with higher birth rates are precisely the ones where people have the opposite worldview of secular, liberal low-birthrate countries? I don't know if I'm coming across xenophobic, it's just that I don't think people in the "first world" actually know how most "third worlders" actually are. You are not keeping, say, gay marriage rights unopposed for long if you're mass importing latin americans raised by devout evangelicals and muslim middle easterners. I see Germany and France already having some public demonstrations of muslim protest over progressive laws, for example.

Learning the local language is a survival skill. It doesn’t require forgetting your first language nor does it mean the end of your culture.

The issue is that groups of immigrants can form enclaves where they speak their own language but not the local language. This has the effect of making them “second class” and limiting both their economic opportunities and their overall contribution to society.

If your population is declining and immigrants aren't even learning the language, it's not "multiculturalism", it's just handing the country over to another culture. Taking into account that progressive values are correlated with lower birthrates, and "regressive" ones are related to higher birthrates, are you comfortable with the consequences of this transition?
Are you sure that things like women's rights are going to stay the same in the long term by substituting the secular population with people raised with religious values associated with high birth rates, like indians, middle easterners, africans and so on? Are you sure material conditions will remain the same by substituting the working class with immigrants from countries with poor education systems, fresh off large scale political instability?

You aren't making 3 meals a day for them because they do it themselves.

They still have to pay for it, though! Don't even try to tell me that an elderly person's regular living expenses — food, housing, utilities, etc. — averages out to less than $15,900/year.

Are you just forgetting those exist? Are you trying to compare the total costs of raising a child, including all living expenses, to only the extra age-related costs of caring for an elderly person, not including living expenses? 'Cause it sure seems like that's what you're doing.

In many cases the elderly are providing the day care for children.

And if it's a multigenerational household where that's feasible on a daily basis because they live there, then they could even save on housing expenses too (maybe even brining down their living expenses to nearly equal to that of a child in the same household).

But we're talking averages, and that's not the average — neither living together, nor providing regular day care. On average in the US, elderly people live separately from their grandkids and only see them occasionally.
