The closest I have come to a definition is to explain that the political ideology of liberalism is one which puts the greed of the ruling class before the freedoms of the working class. I don’t need to argue about definitions to make that point. We live in a neoliberal world. Look around you - you are forced to work for a living, because of free market economics. You don’t have the ability to just go and live or work anywhere you want. Who has more freedom, you, or billionaires?
