What a great advertisement for colonial-era economic relationships! Firestone secures in Singapore “the best rubber in the world with the least waste” (and also the cheapest, because indentured Indian laborers work for low wages on British-owned rubber plantations). “Master rubber craftsmen in the great Firestone factories of America” then make tires which they then sell back in Singapore for a profit, where of course the tires are “at home in the tropics.” Meanwhile the main company which sells the tires in Singapore appears to be  run by Westerners, whereas its subsidiaries on the Malay Peninsula are all run by Chinese.
