Well actually the constitution doesn’t say that. It says promote the general welfare. Nothing about the common good anywhere in the constitution. Do you suppose they are lying?
Yeah it does! It's behind the section that legalizes abortions and sodomy. < /S >
Yes, and the intent of the general welfare clause was not to provide special tax breaks, concessions or class making legislation to privileged groups.
General Welfare in this sense means or meant to the benefit of all citizens. Any exceptions would be unconstitutional.
