'But what was a supportable proactive in her 20s, when a high-paying job meant a decent dispersible income, has become a life-style cramping habit in her 30s; having started her own theatre-production business, Leigh's annual income has dropped to "maybe 20 or 30 grand.

ちなみに、crampingは、形容詞で「筋けいれん」という意味がありますが、そこから転じで、「邪魔するような、弊害となる」。
