I am absolutely with you.I think the reason we are so far adrift from it, is that whilst what you describe might be the objective for the majority of the population, there is a much smaller percentage for whom accumulation of vast wealth at the expense of others is their main objective. This has probably always been the case; but for decades we have allowed policies and created a culture where this greed and favouring of capital has rolled back the progress we made in the 20th century in creating a more equitable society. Worse than this we've encouraged a culture were those a bit further down the ladder from the super wealthy are also able to exploit their fellow citizens without being viewed as social pariahs.
The groundwork was laid for this in the 1980s and we're now reaping as we sowed. Unless something catastrophic happens to wake us up or people consciously decide that they don't want to live in an increasingly inequitable society I fear little will change. Electoral reform might help a bit but ultimately we need to recognise what type of society we are allowing to be created in our name.
Society has to be run for the benefit of the majority.
