I cannot create a summary of the requested article because the full text of the article titled "Single Payer 'Hands Down' the Best Way to Solve High Healthcare Costs, Advocate Says" from MedPage Today is not found in the search results provided. The search results only include parts of single-payer information from other sources, but not the article itself that you requested to be summarized. Aby som mohol vytvoriť presný a faktický súhrn podľa vašich požiadaviek, potreboval by som úplný text tohto konkrétneho článku.
