An astonishing idea for an Isa tax raid was outlined by the Resolution Foundation this week, with the proposal that tax-free savings and investments should be capped at £100,000.

No more aspiring to be an Isa millionaire, it would be £100k and out under this plan.

It said that the nominal money out toward not taxing Isa interest, gains and dividends should instead go in the direction of encouraging those without savings to build up a pot.

Is that a good idea, would it be a fairer way of doing things, and is there any conceivable way this could actually happen? On this podcast, Georgie Frost, Helen Crane and Simon Lambert discuss the proposal and whether it has any merits.

Spoiler alert, Simon strongly disagrees and says this would also perpetuate even greater intergenerational unfairness. Find out why.

Also on the show, the team delve into a new American Express and BA card that's been dubbed the best deal ever for Avios points, but are they worth collecting?

Sam North, of eToro, joins us to talk through what's been going on in markets over the past week and why newly confident investors had their confidence shaken.

Helen fills us in on a very depressing Crane on the Case where Scottish Widows only offered a reader £250 after they were denied their dying wish by its failure to pay out their pension on time.

On a much lighter note, why have we been researching the bleeding obvious this week and testing whether putting a jumper on means you could really save money on your energy bills?

And finally, we are joined by long-time friend of This is Money, Dave Fishwick, who talks to Simon about the Netflix movie about Bank of Dave and what it's like to see your life portrayed on screen.
