Of course true altrusim exists. And there is no excuse for it not to be more frequent.Without altrusim that doesn't have a selfish motive, society erodes like an eventually unrepairable rust.
Without society, family loses it confidence within a generation (and that is what Thatcher neglected to mention or didn't realise).
Because a family is not just a selfish unit selfishly protecting individuals but it is a kind of vehicle through society. If there is no society to be a vehicle through then family itself, rightly or wrongly, becomes regarded as a selfish unit.
And then, finally, without family, individuals lose their confidence.
So, all from the neo liberalist Thatcherist lie that to be 'individual' you must defeat or look down on socialist unions, the destruction of the individual in to scared, dull, superficially nice, neo-liberalist robots. The Conservatives had the gall to run the campaign 'Labour isn't working' about the supposedly high unemployment rate of 1 million under Labour in the 1970s. Within a few years, the unemployment rate had risen to 3 million under the Conservatives. As this means that more people were dependent on welfare, the Conservatives are utter liars about what they think of welfare. They don't mind people being on it as long as it results in more Conservative votes overall.
