Yes it can! Depending on the friend.
One of my besties is the OPPOSITE of me. She’s loaded with a face full of expensive filler, big ass detached house, holidays abroad 5-6x a year, rental properties, wears high heels everywhere, a Range Rover with three XL bully dogs (hate them dogs). She looks like she’s stepped off Love Island and has a walk in closet filled to the brim with designer gear, white carpets, and she works out daily.
Me on the other hand has 2 kids. Live in an Edwardian terrace. Work part time. Dog is a spaniel. Never wears heels unless a rare night out, has 1 holiday a year, no fillers/botox and drives a 17 year old car. Plus my handbag is now a nappy bag whereas hers is Gucci.
Our lifestyles are opposite.
Yet we speak everyday practically and meet up often.
She is the funniest and kindest person. Shes entirely self made which helps as she knows the value of a pound. Shes a hard worker and often works 6-7 days. So she values work. She’s generous and will gift the most thoughtful presents. She mature and savvy. She is incredibly open minded and has ‘lived’. She was once a carer on minimum wage and now a very high up professional.
I’m going on holiday to a caravan with the kids this year. Her and her husband are going to Hawaii. Because she appreciates the value of a pound she is instead excited for us and our first holiday as a family of 4. She’s bought my kids new matching outfits for holiday and gifted me and DP a bottle of champagne to drink on our first night there to celebrate surviving the post partum period with our new baby. So I don’t feel shit about her going long haul 5* whilst I’m in a caravan because her attitude has made me feel good about myself and my little caravan holiday.
She encourages me in my career. Even proof reading assignments I’ve done.
She supports my kids and comes to every birthday/event.
She knows I’m skint on maternity leave so has booked us a spa break on her.
We regularly go to each others houses and just banter about crap and gossip about our work dramas or have deep discussions about random crap like reincarnation.
long winded but my point is, friendships can work with disparity of income or anything else really. It all depends on mutual interests and attitudes.
