Why activity makes me material & full of desires?

I am in very dilemma- When I am inactive or lazy I meditate well, read good religious books etc. But whenever I come into action like studies or useful work I become very material & also get desires to earn a lot of money, respect or other material desires by which I stop doing meditate & completely become indulgent. Can anyone tell me the way to be active & meditator simultaneously. In this current globalized & dynamic world it is huge requirement to be active but that activity makes me material & forget to work for this birth to cross Sansara or Dukkha. So how can I be active & aspirant to dissolve Dukkha/future births simultaneously?
