It's easy to dismiss it if you already own your own home and live a comfortable lifestyle. I'm sure the rising costs of basic food supplies is already hitting the poorest in our society, something I'm sure you have spent a long considering.
I yawn because you think up bad things by yourself, jump to conclusions without considering alternatives and then state them as fact.
1. No, there is not a majority of even the Tory party that want a hard brexit. Are there any? Sure, just like your previous facts that the far right are behind voting to leave - but they are not in control are they? A hard brexit is being considered only as a last resort.
2. If there is a reduction in immigration it will remove pressure on housing and they will become more affordable. This was one of the main reasons why I voted to leave.
3. If there is a reduction in immigration then it will remove wage pressure on the lowest earners and they will have more to spend - not less.
4. Inflation is increasing due to the relatively weak fx rate - yes. But the fx rate isn't outside the bounds of normal fluctuation anyway and when we increase the BoE base rate it will strengthen. It already strengthened just on the hint that the monetary committee is now becoming more hawkish.
5. We only import a quarter of food from the EU and we also export food. We import nearly a quarter from outside the EU. If there are import tariffs with the EU then we'll eat more home produced food and food from outside the EU which will become cheaper when we agree trade terms that cannot be agreed now.
I don't know what will happen. I voted on the balance of probability that things will get better when we leave and there is still a very strong case to make that they will; that the poorest will have more money, that houses will become more affordable... Just try to consider the alternatives to the doom scenario you play in your head. If the worst comes to the worst and there is a hard brexit then there are alternatives.
