Ok, lets put the bickering aside.
Its not impossible to get the status quo changed, it will just take time. The government is aware, pressure is mounting, and slowly it will be fixed. That is pretty much inevitable.
As for where we draw the line... I guess it depends what your priorities are. A tax avoidance issue that doesn't even realistically affect anyone here in any meaningful or significant way... or rising unemployment, healthcare and pension crisis, dramatically rising social disorder and casual violence backed up by increasingly weak policing policies which affect pretty much all of us on at least a semi-regular basis.
That's the kind of stuff I personally rate higher than legally allowable tax avoidance.
