The president isn't supposed to have that much power in the US either. The federal government in general wasn't supposed to have much power; power is supposed to be reserved to the states except for specific scenarios enumerated in our constitution. Unfortunately, a century of blatantly illegal power grabs by the federal government, combined with Congress (which should've acted as a check upon the president) willingly giving their power over to the president, we are in a pretty bad spot. However, if it happened to us it could happen to any country. At the end of the day the constitution of a nation is only meaningful to the extent that people will actually enforce it.
