let's use correct terminology:
the correct term is: Extraordinary Minister.
Saying 'Eucharistic Minister' just plays into their hands.
Actually the correct term is "Extraordinary Minister of Holy Communion."
I will make this easy;
Cardinal Martinez -Somalo the prefect of the Congregation of Divine Worship in 1989 stated that the Holy See viewed the use of minister extraordinarius an unusual occurrence.
The use of extraordinary ministers the way it is being used in the USA is a blatantly wrong and a violation of liturgical norms.
In Pope Paul VI's Immensae Carittatis he clearly defined when extraordinary ministers could be used:
1) The lack of an ordinary minister (acolyte, priest deacon).
2) Lack of ability for health reasons for ordinary minister to function.
3) Enormous number of communicants.
I have been to NO masses with less than 20 people attending where EM's (and more than 1) were used.
