Even renting "fancy cars and dresses, holiday villas and yachts" sounds like an opulent lifestyle, where someone has a lot of disposable income and is finding was to entertain himself with the extra cash.
It may sound like that, but it may be the other way around. Here in Moscow I can rent SmartForFour Cabrio for 720 RUB (10.80 USD) per hour via carshering app, insurance and city parking included. 45 feet sailing yacht on Mediterranean costs 2500 EUR per week and is suitable for up to 6 people, berthing and fuel will add 500 EUR, cheaper than most of hotels.
