If the CCP can make the right decisions, then why not support the CCP?
Do you know the key point? Everyone is a CCP member. It has over 100 million official members, and in every field, almost all those with insight are CCP members.
Even those who haven't joined the CCP think in the same way. People think the same way. This is due to national education and the shared social and historical context.
Therefore, the policies made by the CCP don't seem surprising to ordinary people. "If I were making the decision, I would make the same choice." And frankly, because the CCP can gather the country's best experts to make decisions in a very deliberate manner, even if you dislike their decisions, it's meaningless because the final result will prove you wrong and they right. Why? Because your ability, your knowledge, your insight cannot compare to those of the experts making the decisions. You are equivalent to an ordinary home PC, while the CCP's experts are equivalent to a supercomputer.
So, an ordinary person's opposition is almost meaningless. If you truly want to express your opinions on "how to develop a certain aspect of this country," the best way is to first become a top expert in that field. If you do, your opinions will be taken into consideration by the CCP.
