Or if you're ambitious you borrow money against the house to renovate it and build it larger. Slack off at an easy job and you have energy to do renovations in the evening.
Every 10 dollars borrowed to do renovations becomes at least 20 dollars in increased home value when the renovations are finished, and as a bonus you get to live in the newly renovated house. You don't need to sell, instead take out another loan against your now more valuable house - the bank is eager to help. It's called a "real estate career".
Compare that to working for a living as your "career": Every 10 dollars of productivity you put in for your boss turns to 7 dollars in wages and after taxes you have 4 dollars. Not to mention the taxes and tributes as a small business owner or independent.
Which is the smart move? Which is the fool's move?
If you talk to everyday people, what is their dream? What would they like to achieve? Will they say they want to invent something? Create a huge business? Become best in the world or at least in their region in some sport or hobby? Very few will answer this. Most will answer: "I want to own a bunch of condos and live on the rent". That is the dream.
