With Leo, there's a sense of generosity and warmth that gets spread about. You wouldn't go around helping others out, if you didn't get anything out of it (in this case, it's fulfilling your ego/self-validation/feeling good).
My friend has Libra Jupiter Rx and it's in the 5th house... she's totally into self expression and the arts (Pisces Mars) but she does it to feed her own ego and feels accomplished. Her way of feeling wealthy is that she likes teaching others to make stuff (artistic projects). She was once a tutor for art students. She gardens and really likes it when I come around and help her.
The main problem I see with Jupiter Rx people (no matter what the sign is), they seem to have difficulties with negotiation a high price for themselves. My Libra Jupiter Rx friend (same one) for whatever reason is always super scared to negotiate a higher salary, yet has no problems talking people down in price (she loves haggling with vendors LOL). Same with my Sagittarius Jupiter Rx lawyer friend (he has Gemini Mars)... he can argue and be a complete @ss in court fighting for his clients to get a higher price. But when it came to him and his price, he's ok with getting the short end of the stick! Oh man...
As for the Cap Mars thing... yes, it's earth Mars so you know those people are comfortable with the concrete material world. I like Cap Mars people a lot, they're usually really rational and sound people. I don't necessarily agree with them being the most hard working, as this position means that the native finds comfort and security in work so it's a given. What may seem to be "hard working" to outsiders is actually Cap Mars' hobby/fulfilling their productive egos. Contrary to widely accepted beliefs that they're materialistic- I would argue that they're not. I think they're very ambitious but Capricorn isn't so much into money and material things as they are about status. The reason why Cap Mars works so hard in the first place is to gain power and/through status. Money is and can be just an added bonus. I've encountered a lot of Cap Mars people, with Jupiter Rx too, and they're all about achieving higher levels of everything. To them, it's NOT about the money.
The Mars that is the most materialistic would be Taurus. I mean, that's an earth energy that loves material things and into money but they don't care about status (that's Capricorn's thing).
I have 1st house 0 Libra Jupiter (direct) that trines 8th house 25 Taurus Mars. Take a very material oriented Jupiter and pair that up with the most materialistic Mars- you'd get someone that's like me LOL
I'm not a gold digger, but I love money, material comforts, luxury stuff, beautiful pretty expensive things, etc. I'm not against gold diggers, I actually sympathize with them. I have a few friends who are actual gold diggers and we love fabulous things. I actually tell them how to get more and better stuff out of the men they're with. You would think I have a strong astrological influence that would "bless" me to being a gold digger but I can't stand the thought of being that way. However, I am very good at creating material wealth out of "nowhere."
Let's go back to my Libra Jupiter Rx friend... she was writing up a job proposal and listed how much she wanted to make. Horrible negotiator and really bad writer (Pisces Mercury Rx). She listed a price range as far as how much she wanted to make. She's been a freelancer for 6 years and she still goofs up. She asked me to edit her proposal (which was a complete nightmare) and I ended up rewriting her proposal and negotiated her salary for the job to be $700 more per month than her highest suggested salary. She was shocked that the people actually approved everything! I wasn't.
Now, my friend thanked me for getting her a job and higher pay so she asked the people to get me a small contract job. The problem was, she negotiated for me (without telling me) my price and so I ended up getting paid $300 less/per check than what I wanted to get paid. GGGGGGRRRRRRRRRRR I was really angry at her.
Jupiter Rx people don't seem to mind not getting paid so much, but someone like me... we get super angry about that!!! My lesson learned is that I will NEVER ever let anyone with Jupiter Rx or debilitated Jupiter ever touch my money situation.
