Love and affection is entirely conditional from women, bought with cash or not.
Yes, the only persons who are capable of loving you unconditionally are your parents.
With everyone else, affection is ultimately transactional - people like you for being funny/high status/good-looking/industrious etc. As soon as you stop displaying something that made people like you, people leave.
And here's the thing: displaying desirable traits is directly connected to wealth and status. Wealth buys you freedom, which leads to better health, self-care, interesting hobbies, events etc.
And yes, friendships are still true friendships (or as true as they can be). It's just that people want to be with other people who are on the same level. It's the game of life, where we all unconsiously want to be associated with people who are similar to ourselves or better.
Some women, for example, only want to spend time with high status men because they view themselves worthy. High status men behave in a certain way, talk about different topics than low status men etc. Some only want to spend time with people who are fit and work out.
Imagine two scenarios:
1) Ask a friend to go on a skiing trip with you. Both pay their own share and spend time frugally. In general, there is hesitation to go on a trip like that.
2) Ask a friend to go on a skiing trip with you, your treat. You pay for an upper class hotel, promise nice dinners and fun time. See their face light up, with a big smile they instantly like you more (genuinely even). Now you are a fun person with a nice lifestyle, instantly more attractive to 99% of people.
I didn't invent this, it's how the world works.
