ATM machines and the homeless

I got a new ATM card.  I like its colors; went to the ATM to use the card. The sun was about to set.
The air around the ATM was heavy with the smell of urine.  It is probably the homeless that urinate there at night.  The urine of homeless people is stinkier than the normal urine. The stench definitely has more bite to it. Why is it so?  Is it because the homeless don't get to drink as much water as normal people do? Or, is it because their urine is saturated with anger?
Why are the homeless urinating around the ATM?  I see a reason. An ATM is the most potent figure of the capitalist system.   People have so much money they don’t need to ask anyone for it; the machine spits out cash for them.  The homeless have nothing; they must be mad at such ostentatious display of wealth. Homeless people must be really pissed at they being so poor, while others are so wealthy. And that is why the homeless pee by the ATM at night.  I can smell the anger, and it keeps growing.
