Here’s a thought for you. What percentage of the population wants to be mathematically literate given the amount of effort needed to gain that literacy? In my 30 years of teaching math at the college level the anecdotal evidence I have is that this number is quite low. Why do you think the number of mathematically literate people should be significantly higher than what it is?

What methods of teaching will work for those who don’t want to do the work to be mathematically literate?

You are doing a terrible job at teaching math. but hey, you got your cushy guv-job so who cares about the next generation?

You don’t know whether or not I’m good at my job. A well reasoned response would be different than the one you gave.
