If one is generally entitled to greater deduction by choosing the option of "married filing jointly" after earning income throughout a given year whilst living with their spouse who had not earned any income during the entirety or majority of that year, then why is there even a lawful option to file as "head of household" and claim that spouse as a dependent
You cannot claim a spouse as a dependent when filing as Head of Household. A spouse can never be claimed as dependent.
