I think you contradict yourself. You work, and you say you work hard. OK; I've no reason to disbelieve that. You earned the monies you invested by your own effort and then you invested that money to give you a leg up, as it were. Am I on track so far?
As, according to Churchill, Alfred used both arms and money in his wars against the marauding Danes--stick and carrot, as it were-- you use both your labor and your investments for your benefit. Am I still on track?
I think the writer is not talking about people like yourself who use both the way you do but about a parasitical class of a few who do little if anything beneficial but merely live off their much larger investments and rents and so on. Adam Smith makes the same distinction; so did an unsung contemporary of Jefferson's: John Taylor of Caroline County, VA. Here's something he wrote about these rentiers convincing you that your interests and theirs are the same when they are different:
"The fear of losing property is as strong as the hope of obtaining it. For this reason, the grossest abuses artfully ally themselves with real and honest property and, when attempts are made to correct [said abuses], by exclaiming against the invasion of property and against levelism, and by deceiving the public with fraudulent epithets."
The obscenely rich perpetrate such abuses; I don't see owners of 'real and honest property' doing so as a group. But let me assure you; your interests are not theirs.
