No it doesn't. I spend more on coffee than I do on water. That doesn't mean I "prioritize coffee over water". It means that I don't need to spend as much on water to get what I need.
If you spend over a hundred times as much on coffee than on water every month, and you find yourself chronically under-hydrated, then you may indeed prioritize coffee over water.
Coffee contains water, which makes this a strange analogy. Just saying.
The observation that you are trying to refute is that the FDA falls short of accomplishing its mission and receives remarkably less funding than other agencies of the government that also intend to ensure the safety and well-being of Americans.
In fact, about half of the FDA's funding comes from drug companies. That seems strange considering how the FDA is supposed to regulate those very companies.
