This is UK. My husband is an engineer and believe me, his bring home money is far less than a taxi driver ( don't look at per anum before tax and NI). Don't belittle taxi driver job. Plus it's easy for them to go for jamaah prayer in the masjeed. What a plenty reward for them in hereafter than people who stuck at the office and operation room and cannot attend 5 times jamaah prayer in the masjeed.
