Na, neither I live in UK nor I intend to live in the West, I am quite satisfied living in Pakistan, Alhamdulillah.
Good post.---- I know it's very tough, but at this stage only intention is more than enough.
I know the reality of the civilised world you talking, this civilised world is responsible for the killing of millions of Muslims and other innocent people in the last 100 years. (don't give me example of this civilised world)
We will have to device our own system, in our system (Islamic economics), there's no free ride for the govt as well ---- This system Taxes people as the need arises, if there's no need than no taxes ---- This system also doesn't tax the necessities (current system deliberately taxes necessities).
No need for thin air, for a starter the Govt. must provide facilities from it's own pockets by cutting down on non development expenditures. -- I know, you know and whole Pakistan knows, there's massive massive corruption in govt depts, corruption has kinda become a sacred duty in these depts.
Initiate training courses, information programs etc., for the people --Build trust within the community (the govt is doing the opposite), make them realize Why we need taxes and where tax payers money will be spent.
Note: Islamic State can not tax people for debt servicing as Riba' is Haram.--- The ruling elite is responsible for this, confiscate their properties and pay the interest from it.
