To the Editor:
Donald J. Trump is an historical president, on that we can all agree. He is or was a skyscraper developer who made his fame and glory, as well as a few enemies in NYC in 1968 when he built skyscrapers using the now very common ready mix, continuous flow concrete pouring, that we use here to build elevators. It was faster and much cheaper than the old bucket and pour system that required more steel girders and chains lifting buckets of wet concrete up to each floor. It was a bold move that revolutionized the building industry and made several other wealthy New York families very unhappy.
