It is a plank of the post-modern mood that values are a product of System; and that there are no values outside of System.
If someone asserts values that are not part of System, then these are essentially private, delusional, psychotic - an arbitrary, personal and unshared morality; and such an individual is, of course, potentially dangerous to those who participate in the System morality (dangerous to the extent he or she has power).
And values also include the standards of truth and beauty; so that System defines what is beautiful or ugly, what is fact or lie.
All valuations, in other words, come from System.
This is true; but what is disputable is that there is only one System; and that is the one System of mortal human society in this world - including its cultural and technological elaborations.
The mainstream assertion that governs life in the modern world is that life is material (there is no 'spiritual' domain, no soul, no god/s, nothing 'supernatural'); and that life is (therefore) bounded by biological conception-birth at one end and by death at the other end.
A more recent development of the concept of System is that the cultural and technological elaborations are more real, more objective - because more powerful and widely-known, potentially more stable and longer-lasting, than the human beings of the world.
Thus System has become abstract: impersonal, and indeed increasingly anti-personal.
Because values derive-from System, and the worldly-System is increasingly abstract and with increasing not-human elements (computers, technologies, statistics...); the System can and does generate values that benefit the System considered as an abstract-whole, but not the human beings.
Thus the modern world; in which we increasingly relate to the System only via bureaucracy (systemised humans) and electronic mass-social media. The question of whether this is good for humans does not even arise; because values come from the System, and only one worldly System is acknowledged.
It is either the System or psychosis - and therefore neutralisation, hospital or prison. There can be no exile, no independence; because nowhere is outside or beyond the System.
And, because non-System values are dangerous to the System; anyone with values outside is necessarily selfish and mad - thus will be sought, labelled, and their threat eliminated.
And Yet - the worldly System is arbitrary. It does not have purpose, it does not have meaning: it Just Is.
Thus, modern reality is a mandatory morality, a compulsory and inescapable system of values - that is, at the same time, arbitrary; without foundation, going-nowhere, and meaning-nothing.
Our choice is mandatory meaninglessness or de facto death.
This reality is dawning upon more and more people, because the compulsory System is changing so rapidly, is so obviously incoherent, is so increasingly either indifferent or hostile to actual human happiness or suffering.
Yet, if the System assumptions are accepted - and they mostly are accepted (whether unconsciously or consciously); then There Is No Alternative.
Modern life = slavery to the arbitrary System, with no hope of anything else; becuase there Is nothing else.
All this follows with apparent inevitability, until it is recognised that there is a System beyond 'the System', and which includes and transcends the worldly system.
We then recognise that the wordly System has been and is made by exclusions; especially of God the Creator - and we recognise that there is a transcendent world beyond and containing the material.
We recognise that the supposedly monopolistic worldly System is actually within, and subordinate to, the Divine System.
Once that larger Divine System is recognised; all the above crumbles to dust.
Once we recognise that life extends back before conception and forward beyond biological death...
Once we recognise that this material reality was made by God, from spirit...
Once we recognise that this worldly System is a part of Creation; and may be judged by the values of Creation...
Once we recognise that there is an escape from this worldly System into God's greater reality of Creation - and that most of our lives lies beyond biological death...
...Then we are free.
