False promises, centralized control, Quantitative-Easing Forever, eugenics, Genetically Modified Organisms, Agenda 21, the end of property rights, a New World Order ...
Believe it or not, but some people actually think that a one world government would be good for humanity.
Some are surely misguided while others know the true horror of what centralized global authority can do and will work to manipulate others into thinking it's for the greater good. Don't be fooled.
Be careful what you wish for.
