the point you're making is exactly the reason for the cliche of 'money wont buy you happiness". it is the thought that buying these things (that give us momentary happiness) will equate to long term happiness. in 20,30,40 years, how airconditioned your apartment was (or wasn't) will have little bearing on your overall level of happiness at that point.

also, your last few sentences contradict what you wrote earlier. you said you don't get unhappy unless theres a specific reason, right after you gave 3 examples of you being unhappy without a real reason.
