You sound like a person who has never produced anything of value. Able humans work for the pure joy of producing; wealth is a natural free-flowing result of any-such production. No doubt, the off-spring of wealthy parents become wealthy themselves W/O effort. The logic of allowing that is the 60% / 40% genetic gifting of ability --- so inheritance and marriage both have the same final cause ... identifying and gifting the most able. Likewise a culture allows wealthy corporations to continue producing wealthy because they are also ( until say Y2K ) the most like to product value. Think old 20-th Century Westinghouse, Ford, DEC, IBM, Amana, RCA, HP etcetc.
