The flashiest people I know are the ones with the least money. I know a couple of families that holiday in 5-star, long haul holidays 3 times a year, drive new cars and generally give off the impression they are doing really well. Behind closed doors they are heavily in debt, have mortgages at the maximum and complain about being broke
The flipside to this is that scruffy couple in a scruffy house with one small 3 year old car (PCP and very cheap to run) and one old car both have decent jobs and no DCs so have quite a big disposable income, shop in Aldi, cook from scratch, meal plan and they don't spend on clothes, home improvements, cars or gadgets so have plenty left for holidays. Because that's DP and I that is.
But what is a 'luxury holiday' If you're not there, how do you know how much it cost and exactly how luxury it was?.
A holiday in Mallorca can be 3 star AI in Magaluf booked a year in advance or last minute, a self catering apartment and budget flights all of which will be vastly cheaper than a naice villa in Puerto Pollensa and eating out every night on the Pine Walk. If you see the pics of them near the pool, on the beach, in a bar etc, they'll look very much the same.
