The earliest commercial "talkie" was The Jazz Singer in '27. This Coolidge film is a short, and would have been taking advantage of a new technological advance (soundtrack on the film strip itself).
As to Coolidge's sentiments: Right On!
Adults once managed the world and worked tirelessly to provide a better life for their children. The children remained children long after they should've and now we are rotten at the root.
Coolidge in 2012!
I don't think it is quite accurate to call the United States in the 1920s, the Republic of 1789.
That regime died at Fort Sumter in 1861. Its characteristics included being run by members of the Slave-holding Planter Aristocracy for 32 of its first 40 years and 40 of its its first 48 years. The subsequent Presidents were either Slave owners or subservient to them. The 1789 Republic did not have a succession of northerners to the Presidency until the 1850s, when it was on its last legs.
The Republic of 1865 was quite different. It was Hamiltonian not Jeffersonian. The Federal government became much more active. In the Lincoln Administration alone, laws such as the Homestead Act, the National Bank Act, the Morrill Act (land grant colleges), and the Pacific (Transcontinental) Railroad Act, marked a strong departure from the minimalist norms of the first 72 years. Reconstruction and the 13th, 14th, and 15th Amendments created a new constitutional relationship between the States and the Federal Government.
The Presidency was reserved to Northerners. The first son of the South elected after 1865, Wilson, spent his adult years in New Jersey.
In 1932, the 1865 Republic collapsed in bankruptcy and was replaced by a People's Democratic Republic, a/k/a the "Progressive" Republic of 1932.
In all fairness, the 1865 Republic was done in by its own poor choices, including, the Homestead Act, which filled the Midwest with small peasant farmers who were doomed to fail and become rebellious, the National Bank Act which localized banking on a sub-State level, the consistent use of high tariffs which were jacked up by Smoot-Hawley, and last but not least, Prohibition, which nationalized a social problem, and tried to solve it in a way that simply delegitimated the Republic.
The 1932 PDR, will also fail, unless reformed, because of its out of control spending and its chronically unstable fiat money banking system.
If Obama is elected next week the failure will be sooner rather than later and catastrophic rater than gradual. You do not want to live through that disaster.
The American people are pragmatically conservative (small c) and would rather see the regime stabilized than to see it replaced. If elected, Romney will undertake to stabilize the 1932 PDR. He will have to bring the bureaucracy and the judiciary to heel, cut benefits from the entitlement programs, and raise taxes. Yes, I said raise taxes. He will not do that overtly as by raising rates or imposing a new tax like the VAT. He will do it subtly by cutting exemptions and deductions in the current system and raising fees for entitlements.
We will see, what we will see, but one thing is certain, change will come and it will come sooner rather than later.
You don't see anyone arguing, Fat Man, but it should be noted that hardly anyone remembers who was President from Grant to Teddy Roosevelt, much less in what order. That is a good thing. We were still running of the momentum of the Republic of 1789.1933 was a rejection of it.
1913 and 1920 provided critical mass for our critical mess. It's a Republic, if you can keep it.
