Eh no! The black economy is costing the average UK taxpayer rather a lot. Time everyone, and I mean everyone including the companies, were honest or were caught for their dishonesty. I do hope you are right, that HMRC are brown lettering everyone who has been trading whilst claiming benefits or forgotten to submit tax returns for the last number of years.  If the Government is able to level the playing field the average taxpayer will benefit dramatically and the cost of living crisis will diminish in a fair way.
