Pretend the $20 million is guaranteed, and if anything will increase slightly over time.
What problems could be significantly improved for $20 million?
(I am dreaming of winning the $1.55 billion Powerball drawling. Then taking the lumpsum, posting taxes, investing, and spending 4% each and every year. I understand that the actual may be more, or less than the started amount.)
Giving to the teachers is great. I had looked up my school system's budget and got discouraged, but a few 10's of thousands each as gifts to the teachers and staff is more affordable.
