If elected, I pledge to bring this beast under control through...
Census,
Registration of properties, land and businesses,
Working with the ministry of truth to communicate our will and policies to the people. I'm thinking of:
Public Broadcast systems: Attention! Collect your ID cards and file for taxes naow!
National Newspapers...
If the situation is really really shit, to the level where no one listens short of goons knocking on their door, I think setting up tolls and checkpoints will be a more feasible means than door to door collections. We could combine it with a system of Roman-Style tax farming to keep our bureaucrats loyal through sanctioned totally-not-corruption... But that's a worst case scenario option.
Another variation of straight up tax farming is rent farming. Seize the most important business areas and then grow from there. This is more centralized in execution, but again it's a blunt instrument.
One way to shake up the system and deal with any apathy towards new policies would be to do things like: Attention, all businesses are now illegal unless you purchase a government license. All law abiding business owners MUST register their businesses immediately. Anyone else is subject to property seizure and criminal action...
Once we bring legal businesses into line, we can slowly bring the Urban pops into line. Then work on our rurals, and people on the fringe. Go for highest impact and highest returns first.
DontBanTheMan: What do we have in the way of public infrastructure, public services, cities, ports, rural developments and natural resources?
I see we've tried to tax cars and trains. How are our roads and railways doing? (I propose the checkpoint method to solve immediate collection issues for this, until we can keep tabs on every single vehicle and make people comply with our laws requiring them to register all vehicles.)
Agriculture wise, what can we grow?
