Your situation is obviously very different from this new example you gave. Let me remind you what you said earlier:

You started out this thread seemingly shaken by the fact that your friend "gloated" on your low pay & invited you to join her in her company, i.e. her monthly basic is much higher than yours. You then proceeded to load all sorts of assumptions and finally came out with the conclusion that your pay is the same as your friend after adjusting for amount of work done.

Many forumers disagreed and said that this is an overly simplistic view. Many examples were given on how this leads to all sorts of ridiculous conclusion like tution teacher, SAF regulars earning higher than investment bankers using your method which obviously make no sense.

Then there is also the difference between your company billing by hr and you getting a fixed monthly basic. Again follow your logic lead to another dead end that Starhub engineers should compare their pay by second since their company bill clients by seconds. Of course this is nonsensical & once again nobody was convinced.

You then try to wriggle your way out by claiming all sorts of value to free time with friends, family & friends as well as more assumptions on how much money you can theoretically make with your free time.

Somebody also pointed out earlier your examples are all missing the building up of career potential. You are just taking present salary divide by hours, a lot of people understand that by hour their pay is low, but are sticking around because of the desire to build up their CV which will enable to get much higher pay in the future compared to a 9-5 job in a SME. Junior accountants/auditors in big4 is a good example.

At the end of the day, nobody is faulting your for choosing a lobo 9-5 low paying job in a SME in return for work life balance. Your life your choice. But your various lingual & mathematical gymnastics to rationalize your obviously very low pay into something else falls flat on the face.
