Nonsense, having an ISA means you don't need to concern yourself with the tax treatment of any instrument you have within it. That's the epitome of simplification and harmonization.
I find it baffling how anyone could ever argue against making an ISA available in this country.
I've recently returned to Ireland from the UK. The saving and investment regime here is like something out of the stone age. Everything is more expensive, more complex, more bureaucratic, there's less choice and ridiculous rates of taxation. It's so bad I am actually questioning my decision to have bothered coming back at all.
The ISA is an incredible product and was life changing for me personally, allowing me to buy a house here in Ireland outright with cash. I would put my £20k into my ISA at the start of the tax year, pick my investments (huge choice and so cheap to transact). The platforms available are highly advanced and can essentially be set to auto pilot through contributions/reinvest returns/etc. There's no forms to fill out, no legal/financial advice needed, tiny fees, you don't have to worry about taxes, you just worry about allocating your capital. The ease of use and lack of friction in a massive intangible benefit.
The current investment climate here suits the government and some connected people. The fact that the government
still haven't done anything about something as malicious as the 8 year deemed disposal rule tells you all you need to know about their priorities. If they can't even correct something as basic as that we've no hope for an ISA equivalent.
