I think everybody is missing the point of the question.
There is no rule that says L&W must be greater than T&D. The two sets of forces are completely unrelated.
The T&D could be greater than the L&W of course, but that would be a rare aircraft to possess that amount of thrust - but note that there is no law of physics that says the T&D cannot be greater than the L&W.
Why are the main wheels bigger than the nosewheel? Same sort of question. They don't HAVE to be, but just usually are.
