I am certainly not informed or competent enough on the big figures and secret spreadsheets and books, but I'd still kindly suggest :
1. to cut by a factor TEN or A HUNDRED the size of government and its public "services" FIRST,
2. and, THEN, to see which tax rate remains as deemed necessary (if any)
My name is pronounced like "see real". I code stuff for a living and for pleasure. I care quite a bit about language.
I think America should consider doing the same, and... ASAP!
