Agreed it was far from perfect but better to be outside than in if you compare the trade deals we have now to then.
The only people that have benefited are disaster capitalists (betting against the uk economy),
dishonest politicians (lying to the public and lining their pockets through political lobbying and bribery and working to remove our fundamental human rights (eg exit from the echr)
bankers (restraints on pay and financial safeguards being removed)
large (mainly international) corporations, benefiting from reduced regulations allowing them to slash standards, and trash the environment while avoiding/evading their tax obligations , and
and tax avoidance/evasion for the wealthiest in society.
These are the Brexit benefits but they don’t benefit many of us! And everyone else is having to bare the consequences of the greed of the wealthiest members of our society.
