“From the heart originate evil desires, murder, hate, fornication, adultery” (Mt. 15:19). Usually we tend to blame all on systems and structures, and certainly there are such. But the very origin of evil is in the heart of man. “Greed for money is the source of all evils” (1 Tim. 6:10). Behind every system are greedy hearts that only make a tool of such system to perpetuate their men/women in power.
The solution? Preach the truth, give the truth a chance. “The truth shall set you free” (Jn. 8:32). Most of all the truth means the life and teachings of Jesus. Jesus first gave the example, and likewise taught by word of mouth what He had shown by action, because examples speak louder than words.
