I believe healthcare should be free for all and already basically is with natural wellness diet and lifestyle, Personal Injury Protection (PIP) on auto insurance, Liability Insurance on homeowner’s, businesses, and municipality insurance to cover accidents. On top of that there are crowd funding sites like GoFundMe to help pay for extreme medical needs as well as charities like DoctorsWithoutBorders and StJude.
Wellness with lifestyle and nutrition is basically free because healthy lifestyle and plant-based nutrition creates wellness and prevents or reverses health challenges. However unhealthy nutrition and lifestyle creates chronic health challenges. The current popular expensive high fat animal protein fad diet is linked to obesity, diabetes, heart disease, cancer, and kidney disease. Human beings are designed to live on fruits, vegetables, seeds, sprouted grains and legumes.
Also Personal Injury Protection (PIP) and liability is available on most auto insurance and most homes and public places have liability insurance in case of accidental injury and there are crowd-source funding and personal injury litigation options.
