I think it's sort of unfair to reduce the whole argument to a one-liner like that. Sure, many people do take advantage of generational wealth, setting your children up for success is a basic human impulse. There are also a ton of data supporting the case that actually a huge percentage of successful/wealthy people did not get that way through generational wealth but in fact, just worked hard (also luck plays a factor).

Also, yes the rewards are unfair, life is extremely unfair pretty much all of the time.
