“I feel we should abolish this expensive preposition.”
Are you opposed to learning in Eretz Yisroel because it is expensive? Did your parents not spend money on your bris (the bagels and lox are a commodity), bar mitzvah, and high school tuition (depending on location but still not as cheap as public school.)? Did your in-laws and parents not spend money on your wedding (assuming you are not single.)
We are willing to go the extra mile for things we see as special. Studying the holy Torah in the holy land is certainly worthwhile and valuable.
