First of all, I misspoke with my florid language. What I meant to say
is that I agree the tooth probably should be extracted.
The situation is a bit more equivocal for second molars (the tooth
directly in front of the wisdom tooth--third molar). This is because
root canals are more reliably done, and second molars usually have
longer, more well-formed roots.

The answer I would want to give is very individual. It would depend
upon the condition of the second molar (If you had to upright it, do
root canal, crown, etc., what kind of shape would it be in afterward?
Is it periodontally sound?), as well as your willingness to undergo the
treatment necessary to save the tooth. If the tooth is not contacting
any teeth in the opposite jaw, it is unlikely you will miss it for
chewing. However, if your other teeth in this area are in poor shape
and you lose them too, you may regret having removed the second molar so
cavalierly. IOW, we have to look at the entire mouth.
Of course, the other factor is that many dentists will no longer do
anything like heroics to save a tooth like this. If it turns out you do
miss the tooth, it is likely you can get an implant-supported
replacement later.
Ya, not cheap. The least expensive alternative is certainly removing
the tooth and finding you don't miss it.

Thank you again. That's that what I suspect - due to its position and
condition, it's best left out of my dentition.
I have been told that due to my severe non-diabetic kidney disease as
well as my diabetes that I am a very poor candidate for implants (too
prone to severe infections and healing issues). This was a few years
ago, and my kidneys have only gotten worse, so I suspect it's still true.

With kidney disease I would try to avoid potential hazards caused by
rooth canal treatments / metal crowns.
An additional advantage of pulling the useless molar is that you can
take care for the largest and all important first molar as good as
possible ( keep it clean ) so it will stay in the best condition
possible.
