If a person can afford to buy the toys of life why shouldn't they?

There seems to be a running debate between family members about goods and such. If a person owns a sports car that cost 300k +, a private jet, a pleasure craft like a 80ft sloop or 125ft motor yacht and they did it with their own money why should they be looked down on because of it? If they can afford it why shouldn’t they enjoy it? I personally would not spend $125 on a pair of jeans or $650 on a pair of shoes but if I could I would put out the cash for a sports care worth more than 123k +. If a couple with no kids can buy and keep up a 11 bdr. 6 ½ bath home of 13,000sq ft what is the harm it is doing anyone by them owning it? Just because they get what they can afford do not make them greedy.
