While The West as a culture is clearly suicidal - and suicidal in a long-term, planned and strategic manner - it is interesting to analyse how this arises as an indirect consequence of altruism being the greatest Good, the highest-valued virtue in a secular Leftist society.
While pretty-much all of the other (one-sided and partial) virtues of The Left have by now been discarded, altruism - favouring others above oneself - remains as the ultimate.
And, in a secular context, where reality lacks any objective basis, altruism becomes necessarily subjective and relativistic - which means that altruism has become, in practice, defined in terms of the effect on 'me'.
Since in secular modernity there is no objective concept of doing Good - Good has been reduced to pleasure, and pleasure cannot be measured or quantified in other people - so 'doing Good to others' has been redefined as 'doing harm to myself'.
In a modern, 'relativist' context, without God; instead of doing-good to others; secular Left altruism is redefined as doing-harm to myself.
Modern political altruism is therefore a mass, cumulative consequence of the ethic of 'doing harm to myself' but refracted through human short-termism and cowardice.
That is, a modern secular Leftist sets-out to harm himself - but is thwarted by his own cowardly short-termism, and he ends-up doing harm to other people similar to himself.
He tries to help 'the other' by hurting himself, ultimately by killing himself - but lacks the moral resources to implement his plan on himself - and therefore (guiltily, but effectively) expends great effort and ingenuity personally to avoid the consequences of his own advocated policies.
Because secular modernity has rejected religion, specifically Christianity, then it has no basis for educating, supporting or enforcing the full range of Christian virtues including courage and prudence - and modern culture is notably cowardly and impulsive (short-termist).
So the most moral modern secular people want to be good by being altruistic, and can only understand altruism to be what harms themselves - but they lack the courage, self-discipline and long-termism actually to implement this morality upon themselves personally.
Therefore, modern secular Leftist morality advocates an abstract form of self-harm - in which the advocate can (in a cowardly and short-termist fashion) work towards self-harm and suicide (which he regards as 'altruism') yet in practice to do his utmost to avoid these bad consequences falling upon himself, now.
The typical moralistic Leftist therefore advocates policies which harm other people like himself now - and finds excuses (or just feels guilty - 'liberal guilt') for the fact that his own position remains insulated from these bad consequences, in the short term.
The typical moralistic Leftist therefore has policies against his own interests - his sex, class, race, social situation - but in practice exempts himself as much as possible from these bad consequences, because he is a short-termist coward who lacks the real Christian basis to be anything else.
So we see strategic, abstract 'class warriors' who in practice accept knighthoods and peerages; strategic abstract egalitarians who are the ultra-rich; those who in principle argue in favour of high taxes, yet avoid paying them; white family men who occupy high status jobs but who argue that blacks, women and those of unconventional sexuality should ideally occupy such jobs; those who favour population replacement by mass immigration in the West elaborately cocooning themselves from the social destruction and suffering this brings; those who strategically and abstractly crusade against 'private' schools and health care (i.e. against the possibility of going outside state-controlled provision) yet avail themselves of its advantages; those who advocate a 'small carbon footprint' yet who travel everywhere by private jets and dwell in vast and wasteful mansions - and so on and on and on through all the other gross hypocrisies of the Left.
It is indeed absolutely normal and inevitable for the powerful Left elites to invent ever-more new pseudo-moral policies which are imposed by ever-more laws, taxes, subsidies, regulations and mass media propaganda at an international, national, local and institutional level - yet themselves, personally to evade the ethics they themselves have invented as much as they possibly can.
What seems like hypocrisy is simply moral weakness operating in a context of a self-destroying ethic; secular Leftist altruists believe-in suicide - that is, they believe in the self-destruction of people-like-themselves, but - precisely because they are secular, hence relativists/nihilists - they have no basis for all-round virtue, so they do their utmost to squirm-out-of the consequences of their own policies.
They have enough moral strength for only one virtue, thus any Good which may come from the pursuit of that single virtue is undone and more, by the failure to pursue other virtues and by the unrecognised, denied and unrestrained evils out-with the one-eyed pursuit of altruism.
'The personal is political' means, in practice, that politics is for 'other people', for the general good, for abstract altruism; but not for me.
For such reasons, pursuit of any single virtue always leads to great sin: monomania is always net-destructive of Good.
In secular modernity, the monomania is for altruism - altruism redefined in the only way that secular modernity can recognize.
