I'll agree about the selective employment being practiced right now, by the truth is
the USA has near zero population growth. Company's are way more in-tune with just in time requirements, running streamlined, you name it.

The year's around 57' was the peak of the birth population boom, consider it a postive bell curve, a lot of us are way past that peak - in Life. We are being replaced slowly but the links are harder to fine behind our generation.

Add: they are dieing off and retiring on the front side of that bell curve right now.
