In principle, I would agree with you about taking advantage of the law, sol.
However, to inject some facts into the discussion, the statutory basis for WIC is
42 USC § 1786. According to 42 USC § 1786(d)(1), one of the
mandatory requirements to qualify for WIC is that the applicant has been "determined by a competent professional authority to be at nutritional risk". According to 42 USC § 1786(b)(8), a "nutritional risk" means:
(A) detrimental or abnormal nutritional conditions detectable by biochemical or anthropometric measurements,
(B) other documented nutritionally related medical conditions,
(C) dietary deficiencies that impair or endanger health,
(D) conditions that directly affect the nutritional health of a person, such as alcoholism or drug abuse, or
(E) conditions that predispose persons to inadequate nutritional patterns or nutritionally related medical conditions, including, but not limited to, homelessness and migrancy.
If the applicant does not meet those requirements, they are legally not eligible for WIC. So in this case, we aren't talking about the "spirit" of the program but rather its actual legal requirements.
