I know you mean ‘pakis’ in an intentionally harmless manner, however I think we should make the effort to say Pakistani’s not ‘Pakis.’ If a non-Pakistani was to say it to us, we Pakistani’s would find it offensive and racist. Please don’t be offended by this. 
Back to the topic, I don’t think wanting money is a bad thing nor should anyone with good intentions feel guilty about wanting money. I want money! I am not materialistic but money sure does pay the bills, gives holidays and has allowed me to study a 3rd degree! Lol!
My in-laws live in Pakistan and I live in UK. After marriage, we decided to continue living in London because of money…and why not? I have not forgotten my roots, and even though I haven’t been brought up in Pakistan I speak/ write/ read Urdu fluenty, teach my child the language and I go to Pakistan often. I love Pakistan and I love UK for different reasons - but to me it doesn’t matter what country I live in. I live in London due to fate. Inshallah, I will teach my child to love Pakistan just the way I do…just the way my Grandparents taught me too (who also live in UK.) But in order to love Pakistan it doesn’t mean I have to live in Pakistan.
I don’t think what can Pakistan give me - I think what can I give Pakistan?
Life is too short and full of unexpected surprises, so in this short life I try to concentrate on being a better Muslim.
That’s just my thinking.
