Well, it seems that way to me. It also occurs to me that at the point they seem to be slacking off teaching educational materials, is when they seem to be ramping up the provision of socialist indoctrination.
Not all schools are the same, so I don't who the "they" are that you are referring to.
I don't see anyone "slacking off teaching educational materials."
On the contrary.
I see 4-5 yr. olds expected to know material that used to be reserved for 7 yr. olds.
I see the classroom setting and curriculum designed for the strengths of young girls to the detriment of young boys.
One year of maturity at this young age makes a huge difference, and today's kids are being denied that.
