who can qualify for government welfare?

In 1941, six years after the Social Security Act, the U.S. Supreme Court confirmed who could qualify for government welfare. You never qualified for federal welfare.
• By the way, Social Security is welfare. It is included with all the other welfare programs in Title 42 U.S. Code.

If you were never destitute and helpless, then you never qualified for a Social Security Card. To remain constitutional, welfare (such as Social Security) can only be given to save the life of those who cannot take care of themselves.
— The Supreme Court determined in Edwards v. California, that it was constitutional to transport an indigent person across state lines.
— Supreme Court case Edwards v. California, 314 US 160 at 172, the legal term “indigent person” was given a very limited scope.
— “…must be taken to include only persons who are presently destitute of property and without resources to obtain the necessities of life, and who have no relatives or friends able and willing to support them.”

In other words welfare is only available to save the life of a pauper. Freeloaders cannot qualify.

In order to qualify for federal welfare, funded with federal funds,
• you must be destitute of property
• without resources to obtain necessities of life,
• be so despicable that you have no friends, relatives, neighbors or church or charity willing to give you a necessity of life.

And we know from centuries of legal truth that paupers (funded with public funds) cannot have the rights of a Citizen.
