There is what the Ibn Ezra says and there is you application of his words.
The 2 are mutually exclusive.
For starters:
1. What does he mean when he says “most”? 51%?, 70%?, 99%?
2. What is this nature of this “rishus” he is talking about? You seem to imply that it means theft or shtick. Maybe it means missing out on mitzvos because he is too busy accumulating wealth? maybe it means his bein adam l’chaveiro is lacking cause he is too focused on his money?
3. Is he focusing on the wealthy yidden or goyim as well? (yes, I know goyim cant steal, but this would help us with question 1, namely the percentages)
