If you turn yourselves into mobile phone companies making billions in profits you won't have to pay tax.
Or a local government worker/ public sector worker who tries to undermine the economy by going on strike so people cannot get to work to pay their taxes. Or union leaders recommending strike action during the olympics to further their cause and cause misery to others. I bet if bankers, lawyers, estate agents or removal men went on strike, the public sector worker who had planned to move house on that day, would be in tears and distress.
socialism, communism is a failed idea, it brings down industry, economies, living standards and countries. For Centuries, China's method of government has ensured poverty and misery for 95% of its people, now they have embrassed the free market, it is booming beyond belief, and their tax revenue is manifoldly increased. Their biggest industries have untold wealth and also employ millions upon millions of people.
There is nothing wrong in being a multi millionaire. Imagine all the mobile phone companies out there employing thousands of people who pay their taxes, who dont go on strike and disrupt the economy.
On that point, when we hear about millions of bonuses being paid to bankers. That stat is wrong. most of the millions go to ordinary workers meeting their own individual targets. Like getting a bonus for customer satisfaction, few mistakes, passing exams and progressing and even attendance. I wont mention the attendance levels in the public sector.
Mine and your tax pay for symathetic doctors giving sick notes for anxiety, depression and other long term illneses or public sector workers not turning up for work because they are a "bit ill". (not withstanding genuine cases)
We need to stand up and react to this nonsense. Those who withhold their labour on the grounds of purely looking after themselves is selfish, self centred, not forward looking, damaging and another reason why this country, under any sort of labour, socialist government will not be anywhere near full employment.
To the OP. What have we got to worry about if we declare what we earn.
