The Medicaid program is in place to provide health insurance for people who have very limited financial resources. If you have had health insurance through your job or through a private relationship with an insurer throughout your life, Medicaid can seem irrelevant to you. Plus, when you are a senior citizen, you will have health insurance through Medicare.
All of this makes sense on the surface, and most of us do not think much about Medicaid while we are relatively young adults. However, the program does become quite important for a significant percentage of senior citizens, even those who were qualified for Medicare.
