The minimum wage

In my case, When i was 18 years old. There was one experience on the part-time job.
At that time, I worked in the Lotteria for 2 months and the minimum wage was 2200 won.
But, Nowadays, The minimum wage is 4320 won. It was very surpried to me.
Because, It is about double. But i think it is not reasonable for workers.
In case of korea, Most korean work hard better than other people who ilve in other contries.
Also, I think their work efficiency is better than other people who ilve in other contries.
So, I think the government have to make rules and regulations to mediate the realationship
between workers and companies.
We can get useful information by searching rules and regulations of other nations for the minimum wage.
I think it should be helful to our minimum wage policy.
