Also fears of poverty aren't necessarily driven by any likelihood of actual poverty.
Even some billionaires seem to spend an awful lot of their time worrying about how to hold on to and increase their money, in spite of the fact that the numbers are now just academic.
Entertainers and TV personalities aren't biologically restricted to lucrative but relatively short careers in the way that professional sportspeople and athletes often are, but they know very well that they can fall out of favour and become unloved old chestnuts quickly, so why wouldn't they eagerly grab all of the opportunities that are offered to them whilst they're still in high demand, to set themselves up comfortably both for now and the likely several decades of their lives when they're no longer much in demand?
As this thread clearly proves, there are plenty of people already who really don't like to watch Romesh on TV (like most celebrities); so why would he turn down lots of lucrative offers now, at the top of his game, only to potentially find in however many years' time that even his current fans also find him hackneyed and no longer 'fresh', and he can only get work on the end of Cromer pier?
I'm no fan of Mrs Brown's Boys whatsoever, nor of the Love Island/reality TV lot; but again, I don't blame them for grabbing whatever they can get whilst it's still there for the taking.
