Buying a house isn't for everyone, sure. But this is a serious misunderstanding of what "going into debt" is. You're not buying a TV you'll throw out in 5 years, you're buying an asset class that has a history of appreciating in value over 100+ years that you can get incredible leverage on. In the US and Canada, at least, buying a house for a decent deal (in "normal" times, not at insane prices) is a no-brainer investment.
You mention buying companies...that's just a different asset class, but the idea is the same. It's not valueless the moment you buy it, you now have an asset.
>Buying estate = de facto being in debt for the entire career and then some, plus having to pay all repairs, anything.
Do you think this is all happening for free as a renter? At what point in your life do you plan on not paying for shelter?
