Your post makes it seem like you think sociology and economics aren’t sciences. Economics in Marx’s time was certainly closer to philosophy but that hasn’t been the case since the 1960s.
The problem the Marxists who are not formally educated in philosophy or science face is that they don’t realize economics in the modern age isn’t concerned with the kinds of thinking Marx engaged in because it isn’t based on empiricism.
Oh, so you’re one of those. You don’t know anything about modern economics or philosophy if you think the two are even remotely similar.
Seriously a question in modern economics would be “did the tax policy instituted by placeistan in 2008 positively or negatively impact school enrollment?” While a question in philosophy would be “is the tax policy instituted by Placeistan an ethical or nonethical policy?” Those aren’t the same and the only reason why you would think the subjects are similar is if you know nothing about either one.
Im willing to be you know little about what constitutes a science based on the ignorance you have displayed so far.
Prestidigitation is not part of science and it is weird that you think the inability to predict everything is somehow unique to social sciences.
