Did US Marines die unnecessarily because Douglas MacArthur, Grand Lodge of the Philippines, was chasing Yamashita's gold?

He did return after leading the Allies to defeat the Japanese and kick them out of the Philippines. However, MacArthur may have been so keen to return to collect the riches he knew the Japanese had concealed all over the rugged island nation.

It is said that Charles Willoughby, the general’s Chief of Intelligence, had earlier in the war found evidence of the vast treasures buried throughout the Philippines. According to this theory, Willoughby and his staff had confirmed there were almost 200 Yamashita sites throughout the Philippines, including the all-important Trillion Yen sites.

Various independent researchers have concluded that MacArthur worked closely with the CIA immediately after WW2. Their goal: to locate and retrieve as many of the Yamashita treasure hoards as possible.

Among those independent researchers are prolific authors Sterling Seagrave and Peggy Seagrave who wrote in their 2003 book Gold Warriors: America's Secret Recovery of Yamashita's Gold that General MacArthur “used war loot to create a trust fund for Hirohito at Sanwa Bank” and “also set up the secret M-Fund”.
