Workers have a long history of being taken for granted and trated poorly, but that has improved over time and the EU has broadly been a positive driver of that. But it's ok to disagree with this and/or not see the value in protecting workers' rights.
I don't really disagree with this, but I still don't think workers are treated with enough respect. In some places they are, but not in the majority of low paid jobs of the type that I would get. And maybe it gets worse outside the EU... the fault for that lies with the current government. Another government can come along as protect workers' rights. We don't need to be in the EU to do this, we just need the people to vote for it. And if they don't, it's a regular democratic decision.

As for you stating you would take x job, the fact that you haven't says otherwise.
We're talking about seasonal work here. It's February. I didn't do it last year because such jobs were quickly taken by mostly Polish workers. I do regularly check local job vacancies, and no such vacancies were ever advertised that I was aware of.

You probably aren't fit enough to pick fruit all day long for 3 months, and it's likely you're too lazy.
I disappeared yesterday because I had to walk four miles into Ludlow to catch a train to Leomisnter then another half a mile to the jobcentre to fucking sign on, then go back. Nearly ten miles walking. I'm fit enough to pick fruit, and I'm not as lazy as I wish I was.

The sovereinty/democracy issue is bullshit to me. There's going to be a bunch of people making decisions, we have limited power to impact this: see Iraq war,
We were in the EU when that happened. The reason it happens is because we're stupid enough to vote people like Blair into office. But that's a regular democratic decision. We don't need to be in the EU to have a decent foreign policy, and being in the EU doesn't mean we have a decent foreign policy.

Yes we had the sovereignty to go to war with Iraq without giving a fuck what anyone else thought, I'm not suggesting that the EU are completely dominant in terms of power. They're not. But they do have massive legislative influence, and it's increasing all the time. They control trade, and in turn the economy. An outside body should not be in control of a nation state's economy. That goes for the UK, Costa Rica, Cuba, Germany, every country in the world. It's fundamental to being a nation state.

I don's see much difference between a bunch of people in Europe vs a bunch of People in Britain making decisions.
The regular ability to remove them from power. That's the difference.

This thing about being better off or worse off, that is in the power of the Tories.It doesn't matter if we're in the EU or not. The Tories now have a choice... carry on being Tories by shafting the poor for the benefit of the rich, or do good things to show we were right to leave the EU. I think they want to do the latter, but I question their competency.

For me, as an employer and business owner, reduced workers rights benefit me (thoretically if not actually), lower taxes benefit me.
This isn't a problem for me, quite the opposite. Maybe your business expands and you employ me. If people like you are benefitting, then the economy is getting better isn't it?

Isn't this how reduced business tax can increase tax net revenue? By allowing business to expand faster. it potentially turns me from a net recipient to a tacpayer. I'm no economist, but that makes sense to me.
