To me, have a lot of things in a big problem. Firtly, to have things you need by then. So, you need to use your effort in things. There is one economics principle that affirm: we can do only one thing with money. So, or we buy things or have good experiences, like travel abroad. Both of them, we can’t do, because both need money to do. We need to choose only one.
To make thing we need natural resources. There aren’t natural resources to make things to everyone.
In other hand, simple experiences can be more important than expensive. For example, during my honeymoon, the best memories I’ve had was drinking wine inside the flat or walking in Paris with my wife. It’s very simples. So, to have important experiences we need love, justice and peace. It’s not associated with money or to have loads of things.
