Both socialism and (fiat)capitalism when viewed through the lense of left vs right seem like they diametrically opposed to each other, but when viewed through the lense of centralisation vs de-centralisation, we see infact that the end result is one and the same : more and more power and influence in the hands of fewer and fewer people.
I prefaced the word capitalism above with (fiat) because we do not truly have free market capitalism under a fiat standard.
