Even before the pandemic, young people were already hurting. There’s a serious youth mental health crisis in this country, and we have to do somethin… - Joe Biden

The god's truth is, we are a melting pot.
It is the ultimate source of our strength, it is the ultimate source of who we are, what we've become.
It started all the way back in the late 1700s.
There's been a constant unrelenting stream of immigrants.
Not in little trickles, but in large numbers.

He said they're in America looking for the buried black box, and I looked at him just like you're looking at me, like what's he talking about?
He said they're looking for that secret that allows America to constantly be able to remake itself, unlike any other country in the world.
I said, I can presume to tell you what's in that black box, mister president. I'm old enough now.
I said one is that there is in America an overwhelming skepticism for orthodoxy.
From the time a child, whether they're naturalized or they're native-born, they think about it, a child never gets criticized in our education system for challenging orthodoxy, for challenging the status quo.
I would argue it's unlike any other large country in the world.
There's a second thing in that black box. An unrelenting stream of immigration.
Non stop, nonstop.
Folks like me who are Caucasian, of European descent, for the first time in 2017 we'll be an absolute minority in the United States of America. Absolute minority.
Fewer than 50% of the people in America from then and on will be white European stock. That's not a bad thing. That's a source of our strength.

I take responsibility for the decision. Now some say we should have started mass evacuation sooner and, "Couldn’t this have been done in a more orderly manner?" I respectfully disagree. Imagine if we’d begun evacuations in June or July, bringing in thousands of American troops and evacuated more than 120,000 people in the middle of a civil war. There still would have been a rush to the airport, a breakdown in confidence and control of the government, and it still would have been a very difficult and dangerous mission. The bottom line is there is no evacuation from the end of a war that you can run without the kinds of complexities, challenge and threats we faced. None. There are those who would say we should have stayed indefinitely, for years on end. They ask, "Why don’t we just keep doing what we were doing? Why do we have to change anything?" The fact is, everything had changed.

He talked about how nothing was going to defeat him. How whether he walked again or not, he was not going to give up.
