If your system is crashing so regularly, still hasn't recovered from the last crash, doesn't enable ordinary people to live any kind of life despite them working their lives away, doesn't provide functional public services, doesn't let an increasing number of people even dream of owning a home or retiring, and is actively destroying the planet you live on I think it's fair enough to have some mild criticisms tbf.
Recent events have exacerbated things but the system is undoubtedly broken. Globalisation has had many benefits but it's allowed those with the means to accelerate the "race to the bottom" for those without. I remember Cameron retorting such criticisms by saying it's no good coming out with "Stop the world, I want to get off" and he was supposedly the respectable face of conservatism.
As it stands corporations have more power that governments as it's so easy to relocate if the host country start being a bit mean. There'll always be a country somewhere keen to welcome you with a subsidy and laxer regulations. It needs genuine global partnerships to resolve but that looks less likely than for a long time.
The EU, despite its faults, have tried to maintain standards and have recently began targeting tax avoidance and fraud with the Anti-Tax Avoidance Directive. Not that we'll benefit from any of that.
How Labour challenge that and how they sell it to the electorate is beyond me. Not being front and centre and cheerleading the race to the bottom like the Tories would be something!
