Progress is a logical sequence, the natural conclusion of sequential events. Although the value of the outcome is categorically imperative (determined by the means), the end result may not be the value expected. This is the probable risk of loss–being wrong. If you can’t admit being wrong, progress will not be made, but you can still pretend to intend the progress that yields to your goal, which is a testable hypothesis.
If by repeated testing the goal does not confirm, the means do not fit the ends.
Now, let’s look at Glass-Steagall.
The Glass-Steagall Act of 1933 was repealed because it was considered to be passe’. Outmoded.
Modern financial practices require a more flexible response to the challenges of an expanding global economy. Repeal of Glass-Steagall was considered to be progressive and (like I have been saying) Mrs. Clinton does not favor its reinstatement. (I have referred to this as hip-Objectivism.)
Progressivism is a practical philosophy, accouchered by educators, John Dewey in particular, also considered Positivist.
Dewey is the genuine article, advocating for continuous, linear progression through verifiable (Positivist) means.
The NEA has endorsed Mrs. Clinton, and both are considered to be progressive.
As for the Glass-Steagall issue, Mrs. Clinton, and apparently the NEA, fail the test.
Repeal of Glass-Steagall verifiably set us back to conditions prior to the Great Depression.
It’s a positive progression (confirming a natural-law symmetry) if you are an Objectivist.
