1- we lived without electricity, yes, but we also lived for a significantly less number of years. Just because mankind existed without something for thousands of years doesn't mean it isn't beneficial.
2- if people like making money, then how are they 'swabs'? Seems like they are doing what the love and providing for their family and others thru charitable giving. I don't know what a 'swab' is, I assume that's a negative term to you, but that doesn't seem like a negative life if they like it.
