The Levush Tefillah Paradoxes.

We have to dress the way we would in front of a king. but if i met with a king 3 times a day every week, i would dress relatively casually. but even if you say that one has to dress for every tefillah as if it were a once in a lifetime meeting, i still find problems.
 first of all, there's a difference between the president visiting my house, and me visiting the president in the white house. in the former case i would probably wear dress pants, casual shoes, and a dress shirt. in the latter situation i wold wear a jacket and tie. You could argue against this by saying that every shul/ beis midrash is Hashem's white house, and even when u r davening on the road(or any other applicable nimshal), u have to dress as if u were going to meet him.
secondly, i dont think the Torah ever commanded anyone to be wealthy. a relatively lower middle class citizen who would were a suit to a once in a lifetime opportunity with the president would not be able to afford to wear that for every tefillah. Even if he could wear that one suit that he has, it would become dirtier and more wrinkled and unfit for wearing in front of a king. this defeats the purpose of levush tefillah. and if he did wear that kind of suit every day, he would wear one in better condition if he were going to meet the president. and if he wore a "better condition suit," every day to davening... it goes on and on; i think u get the idea.
so i assume the halacha would tell people to dress according to their class. this disagrees with the hat and jacket principle which says that there is one "befitting for a king" outfit that everyone has to wear. this could be refuted with the fact that poorer people wear hats and jackets of worse condition. this defeats the purpose of the concept of levush tefillah, for Hashem would rather that a lower middle class Jew wear lower middle class clothing, not ripped and dirty hand me down rich man's clothing. (the ibn ezra (i think somehwere during the story of avraham and his malachim guests) says that theres a chiyuv to wear clean clothing during tefillah)
also how could there be a mitzvah to dress like one would before a king if he also has to wear large awkward boxes on his arm and forehead? Even if the king he were meeting was the one who commanded him to wear those boxes, it would still be impossible to fulfill both of those commandments at the same time, and therefore we must not have a mitzvah to wear fancy clothing. (unless you want to be an apikores and say that wearing a hat and jacket is more important than wearing tefillin... :)
i just dont get it. help explain.
