I agree. Most friends would quickly become past tense ones through peer pressure because their other friends would suggest they're toadying. Acquaintances, also riven with jealousy, say at the local pub would be negative at every turn: buy drinks all round; showing off. Don't buy them all round; mean miserable sod. Family members would expect to be gifted a share of the windfall. Slight one or more of them would also result in bitterness. Hand perhaps a sprog or two too much and it could easily go to their heads and they'd become directionless wasters consumed with a hedonistic lifestyle.
Then there's a real prospect of paranoia setting in surrounding personal safety. That too big property would require high walls and being plastered with CCTV cameras for fear of tie-up burglars paying a visit who'd assume there's a safe hidden somewhere filled with valuable goodies.
