It depends on how strong and how healthy is his 比 Bi-jian Friend, 劫 Jie-cai Rob Wealth and whether 比 Bi-jian Friend, 劫 Jie-cai Rob Wealth his wealth stars have protections or not. When strong, healthy and protected no need to work hard and money will knock at your door. And this depend on many other criterias to consider for example their elements, where are all these stars Ten Gods 十神 located in his BaZi, TaYun and years, suppressions, productions, combinatiosn, transformations etc.
Instead of asking whether you have DW/IW, you should find out whether your wealth star (比 Bi-jian Friend, 劫 Jie-cai Rob Wealth for weak self) is strong, healthy and protected. These DW/IW, Output, DO so on all contribute to this “strong, healthy and protected”.
