Brown and Miliband were Social Democrats, Corbyn is a Democratic Socialist. That makes Corbyn centre left and the others on the right of the Labour party, the real left of the party is people like me who tend towards Communist ideology. The problem is the left has been so demonised in the media is that anyone who has the remotest left wing ideology is now classed as a Marxist. Mick Lynch has been accused of being a Marxist ffs. It is all about the eradication of Socialism because Socialism threatens those with the most.
Momentum even at its peak were only 1 in 10 of Labour party members, their influence is vastly inflated in much the same way the militant tendency in the 80s was vastly overstated.
The Labour party under Starmer is being dragged rightwards so that if the electorate want an alternative to the Tories, the alternative is not that damaging to the interests of capital. Starmers refusal to commit to Nationalisation is evidence of this.
This has been going on a long time, since the early 70s in this country when various think tanks were set up using shady money in order to destroy the post WW2 social consensus. Those think tanks flooded the media with anti left wing propaganda , which allowed for the rise of neo-liberalism and what we see now in the destruction of the social welfare state and NHS. The gains made in social cohesion after WW2 cost those with the most and they have fought back and looking at the current crop of Tories they would be quite happy with a return to serfdom.
In my opinion the only way we can fight back is not by imitating the nonsense of the RW but by opposing the RW, Starmer is after imitating them with a few bones for the working class, he does not want to challenge the hegemony of the neo-liberal order because he is comfortable with the neo liberal orthodoxy.
Starmer needs to get out there and say he will nationalise the public utilities and transport systems, he will fund the NHS properly, he will back the Unions,he will fund a proper welfare state and actually say he is sticking up for the working class and not the owners of capital who have taken the piss out of us for so long.
