Marxist naivety

I have just read an article which reflects, in my opinion, the twin failings of  the materialist ideology. On one hand there is an incredible naivete regarding human nature and on the other the classic Romantic goal of creating a workers Utopia often exhibited by those of the materialist persuasion. The piece is titled ' Marxism holds the key' written by John Sutton,(national secretary of the Construction Forestry Mining Energy Union), and reflects his opinion of who or what caused the global financial meltdown.
The opening paragraph of his essay begins with his origins as a poor but morally upright child: "My dad went blind when I was young, so I worked hard from an early age to assist the family" and is de rigueur for someone whose vocation it is to keep others on the right track: "Now the challenge for people such as me is to keep the federal Labor government honest and hold it to its election commitments to implement policies that will create a fairer society".
In this statement he automatically assumes a position of moral superiority. To give him credit he is upfront about his belief that the only true philosophy is Marxism, however when he adds "imperfect and unfashionable as it is today" he asserts his belief as a 'faith'.
He then outlines his position regarding capitalism as: "Working in a union allows you to see the excesses of capitalism. While many employers want to do the right thing, the cut-throat nature of business in industries such as construction forces many to put on moral blinkers. Some do not hesitate to cheat and steal from working people".
What is immediately obvious is that in his declaration of Marxism being the 'truth' he automatically positions himself as someone who is ideologically predetermined to find fault with the business community (capitalism the term his god/prophet/guru coined). One wonders how this helps the workers whom he supposedly represents, which is a troubling issue with unions who are represented by leaders who are more motivated by ideology than by the need to help their members.
The next point of interest I would highlight in this extract is how he automatically assumes employers would 'not hesitate to cheat and steal' without acknowledging that workers are probably just as predisposed to cheat and steal as their employers.This of course would not occur to someone who views human nature as fashioned solely by social and environmental influences rather than the 'fallen' human nature as described by the bible.
Whilst I acknowledge that there are employers who would steal there are also workers who steal, I am also aware that there are many who view fellow humans as 'beneath' them, either by virtue of birth or some other equally spurious reasoning, however this form of elitism is not reserved only for the 'ruling classes' as multiple evidence in history (and literature: all animals are equal but some are more equal than others) have illustrated. There is an equal elitism from those who view themselves as 'workers' or the 'downtrodden' an elitism which Dorothy Sayers termed;'The snobbery of the banal'.
The crux of the essay lies in trying to argue that capitalism does not work and that corporate greed is the cause of our current financial woes.
Unsurprisingly I do not agree with this proposition and would like to suggest that the true causes of these problems lie in the fallen nature of humanity, a condition which occupies innumerable forms and lies behind many worldviews not least the philosophy behind big government (big brother) as well as perhaps that most ubiquitous condition of man which Nietzche referred to as the "Will to power", especially when one considers John Sutton's closing statement:  "It has upset me to see union power weakened in this country during the past few decades. But I remain confident that trade unionism is an enduring concept and that many struggles for industrial and social justice lie ahead".
 respect to the involvement of big government in helping to create the conditions for our current dilemma I would recommend the following link:  http://www.theaustralian.com.au/news/opinion/neo-liberal-greed-did-not-cause-recession/story-e6frg6zo-1225704138278
