I started to notice the phrase 'the most vulnerable in society' becoming much more commonplace 5 years ago and quickly adopted by politicians and incorporated into their political rhetoric. It has become a useful catchall to represent the disadvantaged and is now regularly used in favour of 'the poor' or 'the disadvantaged' or any reference to class. It was used multiple times in George Osborne's budget speech!
The thing is just HATE the phrase. Firstly because it's totally non-specific --- who are these 'most vulnerable' we speak of? One day it's the disabled, then it's mothers, then it's the poor, then its the unemployed. Fine to change the group each time, but it's become a completely meaningless phrase to represent anyone who might need govt support or who might be politically disadvantaged - and the fact is that could be anyone at anytime. And it's a way for politicians to look like they care about 'the less fortunate in society' without actually having to name who they are!
Secondly the phrase is far too emotive (like 'needy') and also paints a picture of the 'most vulnerable' as meek and powerless. For example, a disabled person may be politically disadvantaged and need more assistance but I'm not sure if they want to be painted as 'vulnerable' and 'needy' especially if they work hard to overcome their disabilities.
Please note I'm not stating that I hate those classified as 'the most vulnerable' so don't flame me on this. This is about a stupid phrase that has become far too commonplace that we need to interrogate and ultimately stop using!
