IMO, you can start playing the tape right around the ten minute mark: the preamble about America's "remarkable experiment" bringing "freedom to the world" for "a quarter millennium" is difficult to endure, not to mention the anecdote about his adopted son, but he proceeds to make some important points about "basic math" (in his own idiom) soon thereafter.
This is David Schweikert of Arizona. https://en.wikipedia.org/wiki/David_Schweikert
Despite claims about tax cuts, he argues, the percentage of the economy harnessed by taxation has not declined: the debt crisis is caused, on the one hand, by excess spending but, on the other, by excessive numbers of the elderly and the declining numbers of the young —his emphasis on this latter point is rare.
[11:10] Next year, we're going to have fewer under 18 than we had 20 years ago, and double the number [of people] 65 and up, but are we allowed to actually say that? It's not personal! It's not actually [a matter of] Democrat [vs] Republican, it's just math!
