How about phasing out the simplified Chinese characters and retaining the traditional characters?

[Can someone correct me with the following if it's wrong?]

The traditional characters are used in mainland China for official documents and governments. It has been going on for many hundreds of years. The simplified, on the other hand, the simplified characters were introduced during Mao's leadership.

I personally see no point in understanding the simplified characters at that time when the traditional characters were still present........now people learning Chinese would have to go through the pain of learning two systems for some Chinese characters.....
