Free market? What crap!
The reality is the spin some businesses use now get around any concept of "fair competition"
A typical business today sets up it's HQ in a business friendly low tax economy in the EU such as Luxembourg, puts it's money in an off shore island say the Cayman Ilse, then racks up debt so that the business makes a paper loss thus avoiding taxes.
There are multi-billion pound businesses here is the UK that make a "loss", their HQ is sited to avoid tax and have been bought on debt. Previously the company paid £1 billion per year in tax, now they get tax relief & justify their hiked prices. That money is off shored, funding private jets, mansions, super yachts etc not fair competition, simply tax avoidance.
The reason these rich / business people funded & pushed Brexit so hard was because new EU laws now prohibit this model, off shore tax havens are banned, tax avoidance schemes are being closed down.
Meanwhile is the UK free of EU rules for our benefit, businesses are ramping up roaming charges, bank charges, living costs etc. Mobile phone companies are international not British, they don't pay 'roaming' charges, we do. Come on get real, Brexit was a big lie that 50.5% of those who voted fell for. Oligarchs simply took out injunctions to ban the reporting off this, that is why you don't know, simple as that.
