It is easy to confuse what you want for what you need. There are many things we can live without. It does not mean we should deprive ourselves of them.
Desire becomes a problem when it consumes you. If it turns to lust, then it must be abandoned. Otherwise, the thing will convince you of its necessity.
Simply wishing for better provides a goal. With hard work and perseverance it can be achieved. Be careful of your wishes, for they just might come true.
Merely subsisting would be a life of misery. Things can be enjoyed when not at another's expense. That which is earned is much better than what is given.
