No, what you want is for Labour to say what you want to hear. They are already saying things that you don't want to hear and you are acting like it's some accident and that they should just come to their senses and say the nice liberal things you want them to.
They are vile on immigration because they believe that it appeases a particular bloc of voters and because having scared and compliant legal and illegal migrants means that capital can exploit their labour to even greater extents, in fear they will be deported if they aren't the model migrant. They are discussing it, regularly, but not in the way you want.
Could it be the complex interlocking and stifling nature of Capitalism, leading governments to defund education and drop support for poorer communities? No, it's the technology that's causing cognitive decline. Capitalists are fine actually and can stay as they are.
