I do Biology. I have experienced it. Do you enjoy being rude to me? Do you try to find any reason you can to upset me?
I have experienced the economy. I have experienced banks charging ridiculous ATM access fees, inflated interest rates and big business ripping off the little guy. I have experienced my divorced parents quarrelling over money (ie child support) and abusing each other because of money. I haven't studied economics, but from what I understand, the existence of money makes the average Joe a slave to paper for his whole life while he works for 'the man' (government).
Economics is probably an interesting subject. I am interested in how money influences human behaviour. But I don't want to study economies, because their existence is paralysing.
The OP may be more interested in economics than me and may detest money less. If this is the case, he or she should study economics, as he is uninterested in biology.
