From what I know of the manifesto - these are key points that I have a real issue with and why:
Take illegal migrants back to France and process asylum seekers offshore - completely politically unworkable and extremely costly.
Employers to pay 20% National Insurance on foreign workers (compared to 13.8% for British citizens) - that is discrimination as it would make legal foreign residents unemployable. That is the best proof that they're full-on xenophobic.
Banning students from bringing partners and children to the UK - British higher education is one of our assets, this would make it a lot less attractive. Look at what's going on in the US right now and how Trump is taking the wrecking ball to the Ivy League. It's a demolition business. Reform is not more of a friend to our culture than MAGA is to American culture.
Tax cuts for small businesses including introducing a corporation tax free allowance of £100k in profits and lifting the threshold when businesses have to be VAT registered to £150k from £90k. - on paper I like this one, I'd benefit from this personally but money doesn't grow on trees and it's not clear at all how that's been costed.
£35bn-a-year raid on banks - sounds cool (especially considering previous point) but this risks raising the cost of borrowing for people and businesses.
Scrapping targets for net zero - fashionable sound bite right now... but climate deregulation is real. This is a populist and defeatist angle really. Planet's fucked, head in sand, let's make loads of ££ until we die. Numerous studies have projected a real and very nasty economic shock in the next decades directly due to climate events. And we will see REAL immigration when it hits the fan... Basically the costs will be so much higher if we do nothing. If Reform had a revolutionary manifesto on resources and energy management, I'd talk differently, but they don't. Just like 'drill baby drill' Trump.
Adult social care; Reform would set up a royal commission within the first 100 days of a new government and make a plan - How vague. They're not the only party to want to tackle the issue but there is nothing concrete on the tax incentives envisaged, who would be providing the vital services etc.
It's ALL vague, hazily budgeted soundbites. No concrete, workable solutions to any of the real issues, be it international trade, immigration, social care, the environment. It's hollow.
Scratch under the surface and you find a patriarchal 'white males will fix it' agenda (and British Empire nostalgics). There are numerous hints at a pro-natalist approach and I bet you the 'solution' to a lot of the issues will be to chain women back to the sink. If you liked having a choice, steer clear of them.
