DH's parents are quite well-off. I am in the US, where there are tax reasons that many parents give gifts to their adult children (and, sometimes, the spouses of those adult children) in the amount of about $28,000 per year.
We have received very generous gifts from my in-laws, including a new car that cost nearly 10x what I'd ever spent on a car in my life before I met my husband. They have also helped me pay a good portion of my student loan debt, and are paying for a vacation for us this year.
We suspect that in 2020 they intend to give us the full tax-clear gifting amount for a down payment on a home.
We would not DREAM of asking them for these boons, and sometimes feel a bit embarrassed by our good fortune, but my in-laws are giving these things of their own free will. As they have told us, this is money that we would receive from their estate anyhow. This year, we plan to discuss with them a plan to start us slowly investing in additional real estate with their gifts, so that we could have a continuing passive income by the time of our retirement.
It is our absolute good fortune that this is our life. We and our children could never live so comfortably, or so entirely without fear of the future, were it not for their generosity.
I spent decades below or just above the poverty line, without health insurance, treating illnesses at home as best I could with makeshift supplies and walking to work when my car broke down, or pleading with the electric company to keep my lights on a few more days so I could sell something to pay the bill.
I was actually previously married to a man whose parents were just as well-to-do as my current husband's parents. They were very stingy and mean with their money, and it always came with huge strings attached even for relatively small amounts.
I think this is absolutely the reason that my ExH and I did not do very well economically while we were together ... we found jobs, but they were dead-end, and we didn't have the resources to do better or establish real careers. We have taken the resources we've been given and used them to make our work pay off more. We've also used them to give our children a beautiful childhood, which I know my in-laws appreciate (especially since we are taking steps to ensure that we can be similarly generous with our own children in the future).
That's what you really miss out on when you live in poverty: the ability to take a risk. DH and I moved cross-country to a location with better opportunities, and within a year had more than doubled our income. ExH and I could never have made a similar leap, because we'd have never built up the savings to move without fear of being made homeless before we could find suitable jobs.
I think many parents worry that their children will fritter away any resources given to them. But that's really only true if you have an irresponsible child. Responsible people will use even the most generous gifts in a way that will yield as much long-term benefit as possible.
