Is that sofa really worth another whole week of work?

I fell in love with this sofa at Costco. Before I moved I had decided we would buy it. Now, that I'm here I need to take the term sustainability more seriously. Do I need this couch? No! It would cost almost a whole week of work for my husband. Our income is about to totally change. In San Diego, we were pretty comfortable. Always had money for the things we wanted or needed. However, we are also very thrifty. I don't have a smart phone. We own all our cars outright. The kids wear clothes from resale and thrift stores. I do this by choice. It goes along with my belief of anti-consumerism. In trying to honor my values, I still get caught up in pretty things. My point is, do we really need all these things we work so hard to afford? Part of my hope in our new life is to learn to live more simply. My parents gave me a fine functional couch. Is it pretty? Not really. Who cares? I did splurge on a cute bathroom set for the kids bathroom. I could have bought the plain generic...but the hippos and monkeys were so much cuter. As people, I think we get a little to caught up in the next best thing.
All this glitz and glitter is just used to distract us from the real issues in the world. Teenagers being shot by cops. Genocide. Being poisoned by our food. Health system built to keep us sick. Immigrant children? Does anybody know what happened to them? All I'm saying is there is way more important things to care about than a cute couch. There are a million better things to spend my money on. Step one to sustainability...use what we have!
