Mr A bought a phone for 200,000 naira.
Mr B said he's wasteful because the money can buy a used taxi that could be used for commercial purpose. But Mr B's phone is 40,000 naira
Mr C said that 40,000 naira is enought to start a business.
Mr A paid 40,000 naira for flight and reached his destination after 2 hours.
Mr B said that is a waste of money since a bus would not cost more than 7,000 for a two-days journey
Mr C said, 7,000 is too much and that 1000 naira
for train for four days is reasonable.
The problem is just from one word "levels"
Don't judge others by your level if you're not on the same. And if you're not same on intellectual level, if he's progressive and you're fearful, don't compare indiscriminately.
