Of and for white land holding males to be exact. Roughly the same situation as prevailed in Britain at the time.
One important thing that was spelled out, "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.". I don't want to get into the the whole "creator" thing, but rather, the "Life, Liberty and the pursuit of Happiness", and "created equal".
When the founders said, "created equal", they knew that didn't mean everybody was equal in all things. Not everybody has the same intelligence level, or skill-set or work ethic, or a multitude of other things. That is why they said pursuit of happiness......Not equality of outcome. There was no guarantee that simply being a US citizen resulted in one being successful and happy, just the guarantee that one had the opportunity to do so based upon his own actions. In my opinion, we seem to have drifted far from that sort of belief, that it is up to the individual to pursue. And sometimes that means failure. It is not incumbent upon me, you or anybody else to provide happiness to another that either fails to seek it on their own, or fails to achieve it when they do seek it.
