Good answer

You have my deepest respect, chaps. And they say father's do shit. Damn it, father's are unsung heroes.

When I was a doctor in the service (in Singapore) and still taking specialist exams, waifu made heaps more as she was an accountant with one of the big four companies (also in Singapore - we both pendatang'ed across the Causeway almost as soon as we graduated). She continued to climb up the corporate ladder while I continued to slave away in the public sector until I cleared all my exams (that took nearly 10 years, from 1st paper until all exit papers were completed). She took care of the bulk of the expenses.

Of course, things are different now, she took early retirement last year and I'm the one left holding the fort - so in our case, it was fair: early days, I took shelter under her umbrage (the original meaning, not the new mistranslation), while she's now enjoying the fruits of her labour in the form of a grateful husband who became a success in the latter years in no small part due to her hard work in taking care of the finances and freeing his time and mind and energy to pursue his studies.

So, even if it's $500,000 or even a million per month difference, I say stick with it - because we did it, and we're more successful together as a couple than we could have been apart and alone.

OIC, thanks for your clarification.

I am going to be unemployed in 4 months' time ... if you want to PM me, by all means, and I'll try to answer what I can.

I’ve decided (after a lot of soul searching) to retire early

Part time consulting work, probably no more than a couple of days per week ... this is to keep my mind sharp and stave off dementia for as long as I can ...

Thank you kind sir!
