Okay, but show me what the original TLM was like. The TKLM has been in use in Rome since the end of the 6th century AD. God only knows how much it was changed between that time and the Council of Trent, which specifically forbade any changes to the liturgy. This lasted one or two popes, and then changes began to occur.
As far as the Eastern liturgy is concerned, the OT readings have been moved to vespers and the Great Lent. The variant (Catechumen) part of the Divine Liturgy has two Psalms buried in the Slavonic version. The Greek version may have some too. The Epistle (Apostolos) is on the cantor's stand, read by a lay person. Only the four Gospels are on the altar. The rest of the New Nestament (the so-called deuterocanonicals) and The Old testament are nowhere to be seen.
You did not clarify some of these point. Where is the Old Testament in the Catholic churches located during the liturgy? Why is it not together with the Gospels if both are presumably the words of the same God?
Why are people sitting when the Epistles are read if presumably Paul's words are really Christ's own words? Why is the entire Bible not carried around but only the Gospels?

There is indeed no OT on the altar during the TLM, but there is no NT either. This is evidently another substantial difference between the two rites. In the TLM there is only one book on the altar: the missal. This book contains all the prayers of the mass and all the readings in one big volume - very practical!
What is true is that since the post Vatican II revisions it is now standard for the laity to read the first and second readings. However, the involvement of the laity in liturgical matters has had the unfortunate effect of diverting their attention from the mission, proper to their state, of sanctifying the secular sphere.
