Ther problem with people is often down to perception.
Some here think they have no power and will get fucked whoever they vote for so vote for the guys who will carry on fucking them.
Others vote for people who offer quick fixes. For instance, bringing jobs back to America will force up the price of goods. Double to Quadruple what it costs to make the same product in the West. Are they willing to pay that much to give a countryman a job and slow down the decline of their country for their children's sake?
Some think there will always be opportunities for the brightest. Not thinking there will be another 10,000s bright people in their own country looking for an opportunity and a many more overseas.
Some think the Government should spend more and lower the debt. So here's an idea.
Trump promised to spend more to rebuild the infrastructure. The Government spends nothing and passes all the cost onto Americans who use the facilities that are rebuilt. For instance tolls on roads, bridges, higher charges for electricity, water, telecommunications, security infrastructure, etc. Road charges are easy as are all the other charges. None of this is done with taxes or by the Government. Trump signs it over to Corporations to rebuild and make the users pay for it and provide a profit.
This could be carried through to many other services the Government provides. And there is no getting out of it. Unless you live under a bridge. Your kids go to school, you pay for the tuition, you want police to protect you, you pay for it, you want your house extinguished should it catch on fire, you pay for it. And so on.
Countries in Europe have the same problem. Governments promise things the people can't afford.
