The parents of most of the parents here on CC attended high school between the 1950s and the 1970s.
Also, if you had read through my post, you would have seen that I clearly demonstrated that the requirements for high school in the 1980s and 1990s were also the same or less than they are today:

https://nces.ed.gov/programs/statereform/tab5_7.asp (2018)
Last I checked, the 1980s and 1990s are not “75 or 100 years ago”.
I provide data from 70, 37, and 40 years ago, and you dismiss it as being from “75 or 100 years ago”.
Here is data from 19 years ago (2001):
https://nces.ed.gov/programs/digest/d01/dt153.asp
All of this data still demonstrates increases in the number of required core courses, while non-core courses are nor being added, and, if anything, they are being dropped.
In 2001, only 4 states required 4 hours of math, and 17 states only required 2 hours.
In 2018, 17 states require 4 hours of math, and only 3 require 2 hours.
In 2001, 37 states required 4 hours of English, 6 required 3, and two required more than 4
In 2018 only a single state required fewer than 4 hours in English (and two required more)
In 2001 only 1 state required 4 hours of science, 21 required 3, 21 required 2, and one required a single hour of science
In 2018 4 states required 4 hours of science, 34 required 3, and 10 required 2 hours. None require fewer.
On the other hand,
In 2001, 7 states required more than 1 hour of art (3, 2, or 1.5), 16 required 1 hour, and 4 required 1/2 hour
In 2018, only 1 school required more than 1 hour of art (1.5), 20 required 1 hour, and two required 1/2 hour.
Here you are, incontrovertible proof that the core course requirements have been increasing consistently for decades.
So enough of those false claims of “our parents”, or “we” having had more math or science or English than “kids today”.
