You’re just making excuses for lazy people. The amount of money made, or the time spent doing a job, is irrelevant. The simple fact is that there are more jobs available, than there are people who are looking. People are just lazy and think that they are too good for, or above, menial work.
And when I say janitorial services, I mean cleaning anything. Washing cars, windows, floors, cleaning office buildings. Homes. Hotels. Picking up trash. Anything.
