I find this interesting as I grew up very poverty stricken working class in one of the most deprived areas in the UK. Nobody voted Tory.
I now live a very middle class life. I'm terrified of being poor again. I would say it is one of my greatest fears. I find that life is unpredictable so I take nothing for granted. Especially a comfortable life. I vote to make lives more equal and better. I could not vote to better myself and those more wealthy at the expense of others.
I remember reading Angelas's Ashes* years ago and giving it to my grandad to read. He said that the book reflected his and my gran's childhood: my gran's siblings died because they could not afford a doctor. I think universal healthcare is incredible.
I would hope that however wealthy I became (unlikely very wealthy tbh), I would not forget how fucking awful it is to have nothing and help more than my immediate family by never voting for people who actually despise the working poor.
*I understand it has been discredited, but the working class poverty it represented was real. My family lived it.
