political parties and their cadress

I found a interesting aspect about about the so called party men of the political parties in TN.
i know a person in my area who will fight with you if u say something wrong about dmk. he'll argue with u till u give up. this person earns abt 3k per month. he lives in a slum nearby. his son, abt 12 years old has taken the brush in his hands already. worst part is he'll die one day in this same position, let it be 5 years or 15 years from this day.
if u r working for another party or person who is contesting elections against dmk, he wont support u. even if u give one thousand rupees per day for 10 days of campaign. he lives by his party.
in the same sense im working in a mnc, earn arnd 30k per month. Im looking for a better company to work for in the immediate future if i get a better pay packet.
y is this so, y they r so loyal to their parties, i couldn't find answers for these questions. yes he is illiterate, but after living for 45 years in the place he knows what is good and what is bad, still he is with his party.

these guys amuse me....
