This.That's because your view of what 'social justice' is has been massively warped by the internet.
Corbyn is talking about the huge divide between the rich and poor.
No idea why people are saying that JC "fluffed it" last night. The more I hear him speak the more I like him and his ideas/principles.
As for social justice... it's no secret that even economists and others who aren't left-leaning by any means... these people are increasingly telling us that the growing rich/poor divide is not only unsustainable it's actually inefficient and bad for our economy. Everybody should be concerned with "social justice" of this nature... giving a greater and greater share to the 1% is actually damaging this country's prosperity.
Does *anyone* hear think the Tories will do anything to halt/reverse the growth of the wealth gap? Heck, no. They will either keep the status quo where it favours the well-off, or will actively promote the interests of the wealthy/powerful.
May's "I'm for the working class" is as transparent as could be. If she at all believes what she says, then she must know that her party will simply not allow her to implement anything which could be to the detriment of potential Tory voters.
We need a Corbyn/socialist government because we need to reverse the current trend of ever-concentrating wealth at the top.
