If the topic is power in media and politics, then it's not about money and poverty. It's a valid discussion, but not the one we usually have about money (distribute more, give it to the poor, pay student loans etc).
And regarding your last statement, about reasons and amounts people start businesses from, I can't speak to that because I would generalize too much. Maybe SOME need to aim for 1 billion (is that unhealthy, from a business drive point of view? Do we all have to have the same reasons? I would argue no.), some for 2, some for 10, some for 100. The amount is not important, and it's, again, a place where personal biases show up.
The discussion should be if accumulating wealth is a reasonable drive to start and maintain a business and do the social advantages of that business overcome the disadvantages, do money really trickle down or not, do they really create jobs or not etc.
And also, does just giving people money fix their problems? Could it be possible that it's not only money some of them lack? It could be education, it could be a strong family, it could be self-confidence, could be certain abilities or traits. Could be a lot of things, because poverty and wealth are complex societal issues that can't be solved as simple math (distribution/division).
All of this is not a numbers problem.
