They do have a very nice, privileged life.
They were handed their house on a plate from Anne. A cottage in the grounds of Gatscombe Park which she was given by the Queen.
M will have earned money as a professional sportsman.
Z earns money from JL and other companies she is an 'ambassador' for.
The fact they don't have Royal titles is a blessing because they benefit from a house provided by the royal purse, but don't have to do any tiresome duties.
Z gets to do her hobby- rising horses - and wears a watch (or whatever) to promote a brand.
Sounds blissful to me.
I don't think sticking your tongue out at the press is good behaviour for a 41 year old, even as a 'joke'.
Everyone says (on MN) they seem a nice family. That's based on pics of them watching Z riding horses, or watching horses, or anything to do with horses.
We don't know them.
They certainly have a very carefree life, will never have to worry about money, or getting a job.
