The key to keeping the Republic is that it was made “for a virtuous people” and we are no longer that.
In my mind, the legitimate function of taxpayer-funded universal public education is to teach future voters the founding principles of the Republic, and how and why this country works as well as it does, based on those principles. It’s legitimate, because ignorance of these things would inevitably lead to the Republic’s collapse.
“That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.”
The Left in general, and Biden in particular, should pay specific attention to the "founding ideals enshrined in the Declaration of Independence" that he is apparently so fond of quoting, particularly this passage where it says:
"...We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness..."
This is pretty obviously what Trump was recently referring to in his statement that created such a kerfuffel with the Left and with some on our side who don't get that.
There are a few really important institutions in society that have actually been continually getting worse instead of better.
One of them is government schools which would seemingly make it a top priority for Republicans. But NO. They have failed.
Another would be election integrity. With today’s amazing technology we should be able to have accurate voter rolls and confirmed voters - but it keeps getting worse. The GOP again has failed.
