When in doubt ask the author. 'tis a pity how the true spirit of the Constitution is pretty much gone.
I always like to ask some of FR's resident defenders of the "general welfare" to enlighten us all.
If "general welfare" means that the feds can legislate anything, then why bother enumerating the powers in Article 1, Section 8? I defer to Mr. Madison's explanation...I wish more would but I fear that most of todays voting citizens are blissfully ignorant of the limitations intended on the federal government.
They don't like to engage the issues on such clearly defined terms.
General Welfare is more like the federal highway system -- similar to the Post Office, not everyone directly benefits, but close.
