I'm a layman in law but how does the declaration stack up against the constitution. I'm on the side that the declaration covers the rights not covered in the bill of rights and the constitution. Could an argument made that economic fairness be one of the unalienable rights ?
The Declaration of Independence is not legally binding in any way. The Constitution is the supreme law of the land; any law that contradicts it is invalidated.
Economic fairness is not likely to have been contemplated therein, since it was composed in a slave-owning society. However, international law gives people the right to be free from poverty.
