It's so simply and still some people do close their eyes and don't want to see
Every government is corrupt and looks out for themself, there is not one government on this planet that would not cheat to get in power.
Simply because so much money is involved, being the leading party is in many ways a license to print money. it has been done for thousands of years, cheating for your own benefit is a ultra human thing to do, doing things that will help you is just breed into us.
And even if you belong to a party that has no financial interest
you would still cheat if possible simply because you had another agenda as in Helping World hunger, the warming of the planet, war, poverty... what ever.
Governments are lying and they have always lied, they don't care about you as a singular person.
The sooner you realise that you as a person mean jack shit to somebody who sits in power at some place of this planet holding most of the strings in his hands, the better you be in the long run.
Don't get upset about it, fight it if you want to just don't forget that you will loose most of the time.
