I have more saved for retirement than both of my parents combined, who are in their late 40s.
By a factor of infinity because they have zero retirement savings.
I've always expected that I'll have to at least partially support my parents in their old age, but I'll never be able to afford to support them at the standard of living to which they've become accustomed.
My parents went FIRE a long time ago, but weren't frugal. They always lived beyond their means, and didn't start seriously saving for retirement until their late 40s. They got away with it because my father worked in a very high-income field for several years. They stashed a couple million dollars then retired when my dad was in his mid-50's. They've always been big spenders: getting rid of their debt and stashing a couple million over a period of fifteen years shouldn't be hard while grossing USD$500k a year plus stock options. The fact they saved as little money as they did always saddened me, but they like to live high on the hog and my mother is especially interested in conspicuous consumption. She comes from an old family but due to a couple generations of people having very large families and a policy of favoring the boys with triple the inheritance the girls got, there wasn't much left by the time it got to her.
Presently, most of my parents' money is tied up in two income producing commercial properties. Between these properties, other investments, and all their other sources of income, they make a combined CAD$200k or so per year. (I take partial credit for getting them into investment real estate simply because it's reasonably stable income.)
Unfortunately my folks have always been big spenders, and they make very risky investments. They lost nearly CAD$200k on a type of oil company related security that promised an exceptionally high rate of return, but like many perks that depend on legislation this one depended on a politician keeping his promise to not remove the tax free incentive for the companies offering those securities. My parents persisted in believing there was "no risk", even though I pointed out that politicians lie all the time, especially in an election year. For years I've told them that risk always exists proportionate to the investment returns, and if they can't see the risk so as to accurately assess and mitigate it, they should pass on the investment. But they wouldn't sell because they put their faith in a politician's election promise, and shortly after the election the law changed their investments lost much of their value. At the moment, both of them have large portions of their RRSPs invested in a friend's oil company, which is trading at about 1/6 its former value due to low oil prices. So I presently have more in my 401(k) than the two of them have in their RRSPs. (Why my father is so heavily invested in stock at age 70+ I can't explain.)
To make matters worse, they just bought and moved into a larger, more expensive house and spent about $20k renovating it. Their old house, which is just up the street from their new one, isn't selling as quickly as they'd like because it's overpriced for the market. So they've got about CAD$1.3M in mortgage debt just for their residential real estate alone. They both have health problems, and I think financial stress is contributing to my dad's comfort overall. It's not that I don't love my parents. It's just that they're acting out the old adage about a fool and his money.
