They also tend to only look at raw numbers that look impressive unless you don't think about it too much rather than the whole picture. Grandma bought her house in 1970 for $10,000 and sold in 2005 for $100,000 (made up example). Looks impressive at a glance, however, What's the carrying cost of the house, transaction costs, inflation, and the performance of other investment vehicles during that time period?
This thinking is part of what drove the 2000s housing bubble. Its also part of what causes people to become "house poor," meaning a very large part of their income and assets go towards their primary residence leaving them unable to save any money and have no retirement fund.

>a recent Gallup poll shows that Americans now believe housing is the best long-term investment, beating out stocks, bonds, and gold.
The reality is house prices stay about lock step with inflation on average over the long haul. There's other reasons why I house is a bad investment even if they did outpace inflation. Not that they are a bad thing to buy or own, I am a homeowner myself, its just not a great financial investment.
The American government also subsidizes home ownership in various ways which can play into the fantasy.
>I consider home/condo a utility, a bill paid for purpose; it can go up, but it can also go down.
This is a great attitude. A home can be a fantastic thing to own. It is great at providing housing! It can provide a sense of pride. Its just not a great financial investment and every portfolio should be diversified even if it were.
