To carry this agenda out they recruit potential political candidates from most western countries. They train and indoctrinate the successful ones and then assist them into elected office in their home countries. As this has built up its is becoming easier and easier for them to "select" our political leaders. The list is getting big.
In Canada as an example, the former PM Justin Trudeau, the deputy PM Chrystia Freeland, and leader of the NDP Jagmeet Singh are all WEF. Freeland serves on the board. There are about 30 or so more politicians in Canada that have been elected to federal office and are members of WEF.
The second problem with WEF is their agenda is based on an ideology that implies humans must be strictly controlled, access to resources strictly controlled, overall population reduction. Of course, the elite they represent will sit atop this giant pile of human misery they envision.
There are a lot of conspiracy theories surrounding WEF, for sure. Mainly to do with the Klaus Schwab's "Great Reset" and Covid 19. Klaus Schwab, founder of the WEF, coined the phrase 'Great Reset' - which he used to refer to the economic changes he believed would be necessary following the end of the Covid-19 pandemic. The main source of these theories is their own statements where they gleefully state how Covid created a great opportunity to "reshape" society. Thats when they came up with the posters about "You will own nothing and be happy" and a bizarre campaign to get people used to the idea of eating bugs. That kind of action, using a crisis to force an agenda, and the bizarre media ads is ripe for generating conspiracy theories. It almost writes itself.
The more you look around at the really connected wealthy people and groups, the more you start to see this agenda take shape.
