Yes, yes. I agree that money is one of the things essential for survival and a human being absolutely theoretically cannot survive without money. I get that. However, it doesn't mean you should absolutely LOOT other people of money using psychological "knowledge" (even an engineer doesn't know much about psychology formally, let alone salesmen or hotel management, I instantly recognize manipulation, why try at all? another thought) and since we are a middle class family not having money to pay my healthcare bills, I wouldn't want my father falling for a solar heater scam and me going blind due to not being able to go through LASIK.

I am sick of people out there just wanting money. There are other things that matter too, perhaps not as much, but those are - Family, friends, healthy lifestyle, etc. that cannot be bought with money.
