“If we were to ask which country is the most corrupt in the world, the first answer to come to mind would be dictated by the perceived level of corruption. Perhaps one might think of Mexico, of South American countries, of African countries, of the Middle East or Italy. But the most corrupt is the UK. It’s not a type of a corruption that concerns civil servants, policemen or mayors; it’s a type of a corruption that is consubstantial to economic system. The British economic system feeds itself on corruption. And in the midst of this, the British government and its citizens have not woken up to the plight that their country is going through. A plight greater than earthquakes, greater than terror attacks.”

Attributed to Henry Ford by Charles Binderup (March 19, 1937), Congressional Record—House vol. 81, p. 2528. The quote is preceded by "It was Henry Ford who said, in substance, this," indicating that it was a paraphrase rather than an actual quote. Ford wrote at length in My Life and Work (1923) against the dominance of finance over industry, including a remark in Chapter XII, quoted above, which is very similar to the attributed statement.
