Flavio, you may not think you don't receive anything in return, but there are police, fire & ambulance at your call.  If you rent, you are paying property tax in your rent to fund schools and education, possibly road repairs, water & sewer upgrades which are all conveniences for personal comfort and sanitation. It's very similar to supporting a church with your tithes or giving, you can be putting God before and in many others lives, feeding the poor and hungry, providing help to those without in many various forms.
