In my opinion, I think true financial responsibility is to stop aching on ways to waste your money on trivial things and focus on ways to make more money.
Consumerism is sort of a drug to fill a void. We tell ourselves, I need to have to feel important or valued.
In reality is just an emotion that can be controlled like gluttony, lust or laziness.
People that have a lot of money are very busy. That's because instead of desiring other people things, they desire to work on their business. That's being responsible. Maybe they do it because they don't want to be poor again, but maybe is because they believe their mission in life is something else.
Not saying they are perfect, but my point is that the goal has to be something more than just spend what it took so much effort to build.
