The notice is pretty clear about what they want. Your finances meet the minimums, but that is no guarantee. Apparently, you've been living in the Philippines with your wife for some time. You left that out of your case description, but both that, and your parents being retired, are highly relevant both to the pubic charge question, and for a Consular Officer to understand your plan to relocate and be able to support your wife, including paying for insurance or medical bills.
So, what IS your plan? If you don't have one, consider going home and going to work. Tell them that, and once you are back and working, submit a new affidavit of support.
