A good friend of mine, well-educated, hardworking, etc, grew up with 8 family members in a 2-bedroom apartment.
You don’t NEED a large home. It’s a luxury, and if you buy it it’s because you want to spend on a luxury. If you bought a Ferrari, I would wish you lots of enjoyment and I wouldn’t throw mud at you… unless you claimed it was a necessity and you came back 30 years later saying you couldn’t retire on your own unsubsidized savings.
