How bad will the Budget be?

Plenty of people have said that or I wouldn't be arguing it. 
The rest of your post on immigration (Surprise surprise) seems to be looking for someone who wants to open our doors to Africa so you can repeat how bad that is. Unfortunately for you that person is not me. 

I want immigration drastically slowed or stopped for two reasons. 
1, because I do feel our green spaces are being squeezed out of existence, in favour of building AND arable land.
2, Because I recognise public opinion on the subject and respect that. 
As usual in these conversations I seek solutions rather than just ranting about The government, the globalists, the left, the conspiracy. 
Many find this irritating as it requires them to look at facts rather than rhetoric such as your post above. 

To address your premise based on the idea that immigration (both legal and illegal) wont change. What's your solution? 

Do we just carry on not building enough houses so that the prices of those available take up such a large chunk of peoples income that it destroys the economy? 
Are you hoping to cause civil war by deliberately making things worse? 

Do we recognise the reason for immigration is financial and face the fact that with an aging population and longevity we will have to pay more money to government than we currently do? Or do we think cutting out rainbow crossings and diversity managers will fill the gap? 

Could we look at food sufficiency in a scientific way? Maybe grow vegetables in multi-storey buildings rather than put people in them. Plant fields with woods and lakes to help with climate change and give people the much vaunted contact with nature they need. 

Should we stop further research in keeping people alive ever longer and save the billions spent on keeping them alive and out of pain. 

I'm open to discuss any solutions, but frankly I'm bored shitless with the rhetoric. 

It goes without saying my preferred solution is to stop immigration, but that itself requires solutions to the issues it creates, rather than just bloody lefties, globalists, blah blah blah. 

Great you debate with him then. 
I'm interested in solution not soap boxes. 

LOL he was interested when Starmer was on his soapbox. 

The difference is I have never lied about it, whereas Starmer has you lying to yourself and everyone else as a byproduct.

The point as ever is that relaxing planning rules will alleviate a symptom of the problem not solve the problem. You refer to immigration as a solution to a financial and social problem yet it clearly is only very short term and in the long run, exacerbates as opposes to solves the problem of the aging population. The stats are stark but quite explicit in the conclusions one is able to draw. An immigrant may provide cheap labour and available skills for a period of time but then he begets those who reside in immigrant communities second third and fourth generation. These communities by and large see a higher degree of economic inactivity and unemployment. In fact the old adage that immigrants come in to do the jobs British people will not do is more accurately immigrants come in to do the jobs immigrant communities will not do.

Yes, he made sense. 

Yes blah blah 
Any solutions, By which I mean thought out ones. 

Anything beyond 'that wont work' or 'you're brain washed'?
