The reason people are so concerned about tax evasion now, under the Tory scum, is because the public are being asked to pay for a financial crisis not of their own making, through austerity measures.
Secondly, not only are the public being asked to pay for the casino gambling and racket of financial sector, but we're simultaneously being told that "We're tall in this together".
So people are naturally skeptical and looking for ways in which the the wealthiest and the banks which caused the crisis pay the largest share of the crisis, instead of single mothers, the disabled, the poorest, and other vulnerable people.
George Osborne knew very well that there is an enormous amount of tax avoidance going on:
Why is George Osborne surprised about tax avoidance? I warned of its scale in 2008
As I am on a train from Paris right now I?m only just catching up with this morning?s news about HMRC showing George Osbone 20 anonymised tax returns revealing that just 20 people in the UK have avoided £145 million of tax between them.
The story should not be news. I warned in 2008 that the scale of tax avoidance was far higher than HMRC calculated. This was in my report ?The Missing Billions? published by the TUC that year, in which I said there was at least £13 billion of personal ta avoidance in the UK and a further £8 billion of excess reliefs granted to very wealthy people. www.tuc.org.uk/touchstone/missingbillions/1missingbillions.pdf (apologies ? links are harder on the iPad).

Finally, George Osborne and the Tories will certainly not significantly clamp down on tax avoidance. The reason being that the Tories are ideologically committed to reshaping the economy using supply-side reforms. This means a low-tax regime for the rich and for business, and generally making the UK a 'business friendly environment'.
Even if we weren't in the middle of a financial crisis, they would be ideologically committed to a smaller state and lower taxes.
This means continuation of Thatcher's neo-liberal reforms of privitisation, deregulation, labour reforms, etc. The idea behind this - or ostensibly the justification - is the 'trickle-down' theory. The 'trickle-down' theory asserts, contrary to empirical evidence, that if you keep sucking corporate and wealthy cock, then they will create wealth for the greater good of the nation, which will 'trickle-down' to the masses.
This is what 'trickle-down' theory looks like in fact:
