Help me explain

My brother consistently asks me for my thoughts on things and then will not actually listen to any of it. He voted for Trump and is now asking me what the actual benefits of the DoE is. Can someone explain the benefits of the DoE and what would be lost by it being closed. Explain it like you would to a child, because I’ll be explaining it to a man-child. I’ve only been teaching for 3 years so any input from longer term teachers especially would be very nice.

Edit: links especially to the bullshit he says and/or professionals in the field talking about outcomes would be extra lovely.

Thank you all so much in advance! I truly just don’t have the spoons to try and talk to him anymore, but I’ll take the benefit of the doubt that he’ll actually listen this time if I’m not the one saying it.
