All answered for you already throughout the thread. If you want to believe that politicians run the world, then go ahead. If you want to believe they want what is best for the people of their countries, then go ahead. If you want to believe that elections make a difference then go ahead. You keep mentioning "mature democracy". What does this mean? It is a meaningless mantra pumped out by the politicians and the media but it actually does not mean anything because what we laughingly think of as democracy is not democracy at all. You can never be president / PM if you are not hand selected by the elders of one of a few political parties - these parties are basically the same. Lots of talk at election time, but nothing changes. People get in more debt and poorer. The country gets shitter. The money is funnelled away as fast as they can make it and it all happens under the watch of a load of hand picked toffs and millionaires reading scripts.
As for //// does the government know? What a daft question. Makes me believe you are intellectually challenged, not reading anything, just being deliberately obtuse, or more likely just refuse to believe that the precious elected politicians that you love could be anything other than sold out corrupt money grabbing mouth pieces for the people that actually own the world.
What do politicians aligned with one of the established political parties actually do? What do they really do? Answer? Nothing. Absolutely nothing for themselves, but push through legislation that benefits their party's financial backers. That is it. Nothing else. They do what they are told. Vote how they are told and only occasionally when they go to far do they pretend to listen to the people of the country.
I can not think of a single altruistic act by a politician from the major parties on both sides of the Atlantic. Not one. I can think of lots that have been passed off through the media PR machine as being altruistic but when your scratch beneath the surface you realise it is not.
Next one - Facebook buys drones to connect the world, free, to facebook. Very nice of them, heh? So altruistic to do such a thing. Lovely people.
