Should I?
I can see how economic materialism (i.e. the excessive striving for goods / products) is a societal and cultural problem, but that is just a matter of resources and distribution thereof.
But material existence itself? A problem?
How exactly is it a problem? And why do you think it is?
Its actually a bit broader than what you are depicting.
Any appearance of insecurity (and their subsequent application of defense/protection) on an individual, community or national level is an expression of this problem.
This can take a form from issues of production, social status and/or economics that dictate a certain quality of life to the inevitability of mortality itself.
IOW its the nature of having "something" ( a bank account? a house? a bicycle? a partner? a (hopefully good) reputation? a body?) that one enlists a host of ultimately futile attempts to preserve it.
And what to speak of having it, if one doesn't have it, then one hatches a host of plans to acquire it (or if that fails or is not possible, a host of plans to fool others into thinking we have it) .
In this way the problem establishes a kind of characteristic dichotomy between the mind (the source of attachment) and the body (the canvas that we dress our attachments on) that translates into the literally moment by moment experience of want, envy, hatred, loathing, avarice, etc which is the driving force behind conditioned existence which destroys any hope for a peaceful life and renders "conflict" as the universal language of material existence.
This is the indubitable, insolvable "anxiety" of material existence.
No amount of resource distribution, technology or collective or individual co-operation can hope to solve it (since everything in a temporary world with a temporary ego is simply "here to go")
Its a quality so endemic to material existence that happiness is commonly misunderstood as the temporary mitigation, forgetfulness or outright ignorance of this inevitability.
In short, its practically impossible to indicate a
single problem of this world that doesn't fall under this banner.
