This meme is like having a PsychD diagnosing the heart attack victim with an Oedipus complex. It's supposed to be an exaggerated jab at economics as a science but even under the irony betrays zero knowledge of real economics. It is a science, but it makes you feel better if you can pretend it's all a sham in the same way every other pathetic anti-science dipshit does. But don't take my word for it; take the word of this PLoS One article exploring excessive positive results in science papers:
these results support the scientific status of the social sciences [such as psychology, sociology, economics] against claims that they are completely subjective, by showing that, when they adopt a scientific approach to discovery, they differ from the natural sciences only by a matter of degree.
