This doesn't make sense. Governments want children and immigrants because they need a tax base to stay in power.
As for businesses, they want employees doing things that project stability, such as getting a mortgage (a lot of companies give off time to close one), getting married, and having children. People who do that don't rock the boat and don't speak up because they have a life outside of work they need to upkeep with their paychecks; so they stay good worker bees.
The various forms of collateral you mention (wives, children, mortgages -- the things the Mafia don would ask you about) have a carrying cost which companies would probably rather not pay. And with golden handcuffs (plus restrictive H1-B visas in some cases) the companies may have enough leverage without them.

I don't think they plan that far ahead, because the electoral cycle is only four years long. It's like issues of national debt: You may have a momentary crisis, but you find some path of low resistance out of it (issue more debt), and keep going. That works because the rest of the world is happy (for some reason) to keep buying up the debt. Demographic issues can be papered over similarly, so long as the money -- the same money, ironically -- provides an incentive to come.
(It's also worth considering that, since Reagan/Thatcher (and arguably Carter, though in many ways he seemed like a good man), the State has lost power to the Corporation, so even if the State does pursue longer-term interests, it may not play a large enough role in day-to-day life to have an effect.)
If you're just following gradients, I think this is the basin you stay in. But it feels like some kind of behavioral sink.
> In Tudor England the ever increasing demand for wool had a dramatic effect on the landscape. The attraction of large profits to be made from wool encouraged manorial lords to enclose common land and convert it from arable to (mainly) sheep pasture. The consequent eviction of commoners or villagers from their homes and loss of their livelihoods became an important political issue for the Tudors.[44] The resulting depopulation was financially disadvantageous to the Crown. The authorities were concerned that many of the people subsequently dispossessed would become vagabonds and thieves. Also the depopulation of villages would produce a weakened workforce and enfeeble the military strength of the state.[44]
From this my mind goes to the Highland Clearances [2] (and to America's Rust Belt and England's North).
In both cases, capitalists were more than happy to replace people with sheep, because that's where the profits lay.
The interesting thing about the quote above, is that it fits the pattern I mentioned, in which the interests of capitalists are not exactly the same as the State's.
