Evening CJ.
The US taking care of their veterans can be traced back to 1636, when the Pilgrims of Plymouth Colony were at war with the Pequot Indians. The Pilgrims passed a law that stated that disabled soldiers would be supported by the colony.
Then the Continental Congress of 1776 whose members campaigned and encouraged men to enlist during the Revolutionary War, also provided pensions to disabled soldiers. But it was individual states and communities that provided direct medical care to veterans. I know personally my ancestors who fought in the Revolutionary war were provided with allotments of land in the Ohio territory for their service but it was individual states and communities that provided direct medical and hospital care to Veterans.
Following the Civil War, many state Veterans homes were established where medical and hospital treatment was provided for all injuries and diseases, whether or not they were the result of an injury from war. The key word here is "state". All veterans from all wars whether Civil War, Indian Wars, Spanish-American War, etc., received care at these homes while the federal government expanded disability pensions to include spouses and children. My ggg grandfather fought in the Revolutionary War in the Virginia Militia. He received an allotment of land in the Ohio territory. Later three of his four sons fought in the Civil War and all received allotments of land for service in the state of Ohio. My gg grandfather was wounded in battle and I know exactly what the government pensioned him including wife and children. His farm is still operating in Southern Ohio by a family descendant just outside of Portsmouth on the Ohio River and he and his wife/children are buried just up the road. The old homestead has been well preserved.
When big government progressive Woodrow Wilson was in office, and WW1 was upon us, he and Congress established a new system of Veterans benefits, including programs for disability compensation, insurance for service personnel and Veterans, and vocational rehabilitation for the disabled. The key point here is "states" were no longer in control of the medical. By 1921 all WW 1 vets were under fed programs that created the Veteras Bureau. All public health services to veterans were transferred to the bureau.
The second consolidation of federal Veterans programs took place around 1930, when President Hoover elevated the Veterans Bureau to a federal administration that created the Veterans Administration. At that time, the National Homes and Pension Bureau also joined the VA.
What I am trying to get at is when states cared for immediate medical needs of vets whether war related or not, it was more efficient for the vet. But thanks to Wilson and then Hoover it evolved into an overbloated, inefficient federal bureaucracy that is not serving the vets today well at all. Let the feds focus on the pensions etc and let the states focus on the medical needs of the vets. It seemed to work quite well till folks during the Progressive Era started tinkering with it.
