Pretty much everybody has the feeling that their income is "only sufficient to scrape by in a moderately convenient way". In the end, of course, they're all wrong: no income is enough to keep you alive. What good does homeownership do you once you're dead?

You're comment points out very effectively that this is an illusion. I'm sure you're aware that the other 90% of the people in your country are also at least scraping by, even though many of them have an income that is a fraction of yours. Do you suppose they spend all their time missing the conveniences you take for granted? Unless those conveniences are things like access to surgery and adequate food for their children (do you live in Zimbabwe?) probably not.

So consider whether the conveniences that account for the discrepancy between their scraping along and your scraping along are really worth the inconveniences required to buy them.

If you're like 90% of people, you never will consider this seriously — because if it wasn't crazy, everybody would be doing it, right? — until it's time for you to retire.
