Barry, you're better off taking your lumps than pointing to the actual context, which reinforces the point that you have no clue what it takes to run a business nor where the tax base truly comes from.
So he wasn’t talking about public financing of the infrastructure that makes business possible? Hoo-kay!
The “actual context” was
“You don’t deserve the fruits of your labor because others helped you along the way. This justifies my policy of rapacious taxation rates on your profits.”
This is exactly what he said, what he meant, and what no supporter of his would EVER admit, though it is the core of their ideology.
