He was right to mention those four cases of our medical system's failure.  But he stopped before he got to the part where the replacement plan would not change a thing.  I have yet to see anything that guarantees any care to anyone, or that will contain costs.  No matter the plan, there is not a single one that can meet 100% of the needs of 100% of the people.  The only thing Congress can do is take its time, work collaboratively, and try to foresee as-many consequences as possible, then address them.  Or better yet, simply fix the parts of the ACA that have proven not to be mostly beneficial.
