The Constitution’s intent
In reviewing the intent of the Constitution, we must look at the context in which it was written. It was conceived when the Industrial Revolution was just beginning.
I don't know if our founding fathers even realized it was occurring. The steam engine was invented, but I have no indication any of them were aware of it. The primary sources of power during the time were water, along with horses, wind and slaves. The fathers had no idea of the changes the Industrial Revolution and capitalism would bring to America. The Constitution provided for slavery and bond servitude, and denied the right to vote to women and freed slaves. Freed slaves had no recourse in the courts.
"The Federalist Papers" were a series of essays expressing the opinion of a few people and had no standing in law.
The Constitution provides for a Supreme Court to determine intent.
How is the Constitution going to "promote the general welfare" if it allows major corporations to make billions of dollars off the backs of exploited workers while paying them below-poverty wages? Everyone benefiting from welfare does not "live off others' work while raping, robbing or shooting anyone who doesn't freely give them whatever they think they deserve."
I, too, believe that anyone who can work should work, but we cannot change the status quo by simply putting innocent children on the street to starve.
We can begin changing the institution of welfare by paying a minimum wage which provides a livable salary, gives people hope for a future, and gives these people a reason to get off welfare and food stamps.
