Since consumers need producers and producers need consumers, you really can't argue that either one is inherently bad.
However, I would argue that our intent should be biased toward producing, since producing helps us grow. Consuming in this context has connotations of passivity, and while rest is important, too much rest will make us weak. Also, when you are consuming you can be mindless. When you are producing, you stretch your mind. Not only do you have to think about how to meet your goal, you have to think about what you are producing in context of value and other people. It's mind-expanding.
Also, it is natural for us to want to grow, so if we spend most of our time in passive consumption it will negatively affect our mood and sense of well-being in the world.
That wonderful book you read? It wasn't created by someone reading; it was created by someone writing. If everyone read Wikipedia and no one wrote Wikipedia, there wouldn't be anything to read.
It's about focus and goals which can only be achieved by concerted effort over a long period.
Instead of "producer" and "consumer" I could have said "force of nature" and "hopeless stimulation junkie".
Whether or not you make anything of value to exchange with other people is not really important. How much you're consuming is also pretty irrelevant. The important thing is that your brain is in "make things happen" mode, not "stimulate me" mode.
I wasn't writing about economics, I wrote about you getting what you really want out of today and not having your attention and focus stolen.
