The whole "it's always the gringos" thing is a giant fucking cope.
That some people adopt the ideology later doesn't take away from the fact that this shit is imported from the first world. It is the gringos who impose it.
How in the living fuck do you make an "energy efficient" stove?
You make it work under different principles. A lot of the heat from fire stoves floats away without doing much. Inductions stoves are more efficient. I think that's the idea behind these kinds of moves.
That'd be the second one. The biggest one is killing as many people as one can.
