Actually, worldwide the richer have been getting richer. In Western countries like the US and the UK, they have been doing this in part through tax avoidance and outright tax evasion.
As for 'the clever getting richer', I have to ask what was so clever about the lemming-like bankers who drove the global economy into a nosedive? In the UK they seemed to have retired early, using their amassed wealth to sit on their fat, parasitic arses while living a comfortable life doing absolutely nothing of value to anybody.
Fair enough. I was sloppy in my language. They threaten to leave (for instance).
First off, it's not tax avoidance or evasion if what they are doing is legal.
Second, its sounds to me like you're describing welfare recipients. The only difference being that they never, ever, contribute to society, whilst the rich worked to get their fortune and have the right to retire and enjoy the fruits of their labor.
