I have observed that if you increase your needs, the new 'increased need state' becomes your new norm after a while. For example, if you didn't have car before but then you purchase it, use it regularly and then when you don't have it anymore — you'll miss your car, you'll feel like you can't live without it even though you managed to live without it before.
Do you agree with this observation? Would you agree that it's better to not increase your needs in first place?
You have given a great example. Our needs are unlimited. In the past, there was a stage where people could not fulfill their basic needs, yet they tried to survive and they survived in society. Today, there are many poor countries in the world who are unable to fulfill their basic needs, yet they have sustained themselves and are living in harmony in the social context. They have limited their needs because they do not have enough money.
As soon as you manage one need, another need will appear for you. If you are able to fulfill the basic needs of the family well, then there will be an additional need and if you have a house, there will be a need to buy another house. Human needs are unlimited but they are limited in terms of ability. Instead of getting carried away by the abundance of wealth, every person should adjust to his or her own wealth.
