Development is the key to solving all the problems of our country.

Is this right or wrong?

Right!

But now many people have misunderstood this sentence!

In other words, the person who has the obligation to explain failed to explain it well!

Everyone has learned about necessary and sufficient conditions in junior high school.

This sentence expresses necessary conditions, not sufficient conditions.

Putting economic construction as the center is necessary but not sufficient. That is to say, if we do it well, we may not be able to achieve long-term peace and stability, but if we do not do well in economic construction, we will definitely not be able to achieve long-term peace and stability. The last sentence is the same. Do you understand?

Now the leaders just confuse everyone's thinking and do whatever they want under the guise of economic construction.

Luxury cars are used for public transportation for economic construction; public-funded receptions are for economic construction; public-funded "inspections" abroad are for economic construction... Economic construction is only a necessary condition, and it is indeed important, but they did not tell the people that they only do a good job in economic construction and other things

If you don't do it, you won't be able to achieve the beautiful goals they originally preached to everyone.
