“三代从商不如一代扛枪”指的是，第一代、第二代从父辈继承了家族的商业，但第三代没能像第一代、第二代那样成功，只能扛枪警卫。这主要是由于经济的发展和家族商业的老化。
随着工业化的发展，许多高科技产业和服务业的出现，使得传统的家庭企业不再具有优势，有些甚至被迫破产或转型。这导致了家族商业的衰落，第三代继承人无法像第一代和第二代那样继续创业，只能转而从事其他行业，如保安等。
所以，“三代从商不如一代扛枪”主要是由于经济的发展和家族商业的老化所致。家族企业衰落，使得第三代继承人无法像第一代和第二代那样继续创业，只能转而从事其他行业。
The saying "three generations from business are not as good as one generation from soldiers" refers to the fact that the first and second generations inherited the family business from their parents, but the third generation did not succeed as the first and second generations, and could only gun security. This is mainly due to the development of the economy and the aging of family businesses.
With the development of industrialization, the emergence of high-tech industries and service industries has made traditional family businesses no longer competitive, and some have even been forced to bankruptcy or transformation. This has led to the decline of family businesses, and the third generation of heirs can not continue to start their own businesses like the first and second generations, but can only turn to other industries, such as security.
So, "three generations from business are not as good as one generation from soldiers" is mainly caused by the development of the economy and the aging of family businesses. The decline of family enterprises has made the third generation of heirs impossible to continue to start their own businesses like the first and second generations, and can only turn to other industries.
