Or how much it differs even within countries ! <| sep |> On a practical level , I could agree with that . On a moral level , I cannot . The problem with assigning rights like that is , who provides them ? If I say you have the right to freedom of speech , or your liberty , that does not require the government to give you anything at the expense of another . But shelter , food , water , medical care , those are products and services that require constant action and effort from others to produce provide . If I say you have a right to them , does that mean you can force those professionals to provide you with their products and services for no charge ? The other way to do it , as is normally done in welfare systems , is through collective taxation . But that ' s still money being spent on you from people who were unwilling to give it to you to begin with . That to me will always be morally repulsive , and so I cannot support it on those grounds .
