"That" being "..... this unbelievable American system that we have that allowed you to thrive. Somebody invested in roads and bridges.", not the business they created. As was pointed out a few sentences later, "The point is, is that when we succeed, we succeed because of our individual initiative, but also because we do things together. ".
What he ACTUALLY said was what I quoted, and:
"If you've got a business, you didn't build that. Somebody else made that happen."
He wasn't talking about roads then, he had moved on.
Twisting his words doesn't change them. Mine are direct quotes.
