Stellar Astrology (Nadi Astrology) is a predictive system of astrology which gives importance to houses, constellation & sub lord signified by a planet depending upon its degree in the astrological chart. In this system, a planet gives results not on the basis of its natural significations or the houses it owns but on the combination of houses signified by the planet, its constellation lord & the sub lord. A single house is not capable of giving any result & it is very difficult to assess results of a planet without looking at its constellation lord & sub lord. For eg: Second house signifies a number of things but we cannot pinpoint anything unless we see the other houses that the planet is signified through itself, star lord or sub lord. If the planet is also signifying the eleventh house, then either it can mean "Gain/Addition of a member in the family" or "Gain of money & assets" - those who follow astrology knows the second house
This methodology of knowing if a person is meant to become rich is not a theory, it is actually practiced and applied on horoscopes to predict about a person's life and to figure out if a person is meant to become really successful and will become rich in his life. In a horoscope, there are 12 houses and 9 planets (excluding Uranus, Neptune and Pluto). Most astrologers see 1st, 2nd, 5th, 6th, 9th, 10th and 11th house, and their lords to see if a person has the capability to become rich and successful. Some also take the benefic aspects from Jupiter, Venus, Mercury and Moon into account.The actual answer does not come through this way. To accurately know if a person is meant to become rich and successful you need to see these three things: The Person's Intelligence Benevolence of The Planets Support from The Time When these three things combine then a person actually becomes successful. I am sure that you find this very logical.
