The past cannot be changed.
The present is a product of the past
The future? The future is best described in A Christmas Carol, a fact those elite in the western world need to remember:
"Before I draw nearer to that stone to which you point," said Scrooge, "answer me one question. Are these the shadows of the things that Will be, or are they shadows of things that May be, only?"
Still the Ghost pointed downward to the grave by which it stood.
"Men's courses will foreshadow certain ends, to which, if persevered in, they must lead," said Scrooge. "But if the courses be departed from, the ends will change. Say it is thus with what you show me."
The Spirit was immovable as ever.
Remember this quote, as you read this story of President Obama bragging about America's non-white future. [Obama: ‘This is going to be a browner country’, Yahoo!, 12-19-16]:
Regardless of what President-elect Donald Trump’s plans are for immigration, President Barack Obama says there will be “inevitable” changes to the demographics of the United States.
“If you stopped all immigration today, just by virtue of birth rates, this is going to be a browner country,” Obama told NPR’s Steve Inskeep in an interview that aired Monday. “And if we’re not thinking right now about how we make sure that next generation is getting a good education and are instilled with a common creed and the values that make America so special and are cared for and nurtured and loved the way every American child is treated, then we’re not going to be as successful.”
