Thinking that evil infiltrated the US government, medicine, schools, courts, etc. is only seeing the tip of the iceberg.

Evil used government, courts, medicine, churches, schools, banks, charities to infiltrate God's world.

The whole concept of government is an infiltration. The whole concept of medicine over immunity is an infiltration. The whole concept of a church as middleman with a single truth is an infiltration against direct connection to God and individual truth. The whole idea of public education memorizing someone else's beliefs instead of realizing through experience is an infiltration. The whole idea of money to facilitate taxing commerce instead of barter is an infiltration.
