I think Eva Wiseman (Observer) is right, the term (and # here) #costoflivingcrisis has lost much of its meaning through our continual (if understandable) use... so can I suggest we might move to one of these alternatives:
#enforcedpoverty
#engineeredinequality
#economicwaronthepoor
I'm sure you'll be able to think of some others...
but what we need is a term that has the immediate traction of the 'cost of living crisis'.
Over to you!
