The average Joe has always been susceptible to the lure of false of hope - and most likely always will be, so I agree with you in broad terms. But, the amount attention the voting body, as a whole, pays to politics does change. Generally speaking; people tend to be more involved when their own economy is less than they think it should be. I would certainly advocate that people take a greater interest in their democracy at all times – but, that’s just a pipe dream.
I have been the exact opposite of that. When I first got married and we had very little money I cared very little about politics. I was to busy working trying to support a young family. Now that I have become wealthier I have a great interest in politics and the "issues discussion" or lack thereof.
