Politics has become a business in some number of countries i know. Where people from younger to older age are all affected. They are doing politics to gain their power. In all these countries murders, fights, thefts, robberies have increased because they are doing these bad activities using political power.
Disadvantages of politics:
1. The number of your enemies will increase
2. It will be a waste of money.
3. Your time will be wasted.
4. You may have the possibility of death.
The comment is quite relevant at present. The problems you mentioned like: increasing hostility, wastage of money, misuse of time and lack of security are the realities of many countries today. Abuse of political power has become a serious problem in the peace and order of any country. Politicians should be doing the welfare of the people and not abusing power. In this case, the electoral system should be made more transparent, fair and accountable to the people. Government laws against corruption, murder, criminal activities should be enforced more strictly. People are the biggest force, their collective efforts can build resistance against negative politics.
