WT is a dooms day cult organization with American centric view of the event as any other crazy religous groups that originated in USA in the past 200 yeas (think mormons, adventists, and others). They attempted to explain Scripture with the same reasoning as other Christian groups without ability to get satisfying answers. Catholic, Orthodox, and Protestant churches trying that for centuries. Yet, some obscure religious group like WT think that they will get the answers, something what much larger and powerful religous groups like Catholics were unable to do so.
WT since the time of Russell were preoccupied with earthly paradise under supervison of the Old Testament prophets and king. They believed in the restoration of Eden with disregarding the finite space and resources on this planet. Nonetheless, Russell believed that 144,000 will go to Jesus' kingom in heaven:
He ordained also that a certain specific number should be chosen from amongst men to be his joint-heirs in the Kingdom--participants with him of the New Creation. We have every reason to believe that the definite, fixed number of the elect is that several times stated in Revelation (7:4; 14:1); namely, 144,000 "redeemed from amongst men."
144,000 is a fixed number, not symbolic. The number of sheep:
If we multiply the number of square furlongs in the city by the 144 measures of a man the result is 144,000,000 by 144 or 20,736,000,000, the estimated number of the sheep class at the end of the Millennial Age.
Since its foundation WT was obsessed with numbers, numerology, and dates, and will attempt to model its theology upon it. On the end, it comes down to business, since 20,736,000,000 individuals (2.5x or present world's population) would require a lot of printing and publications.
