I don't mind people agreeing with the slant because it is a fair economic argument to make but to just mark me down for pointing out the slant is harsh IMO.
That video was full of stuff complaining that you get taxed on EARNINGS from investments and trying to equate that to being taxed twice on the same principal sum. This is nonsense.
You're being taxed for earnings and then earnings made from those earnings. That's two separate sums.
The chap was trying to make out that people were being punished for saving as opposed to spending but failed to consider consumption taxes such as sales tax or VAT (in Europe). You don't get punished for saving, you place your money in the bank and it remains there, no punishment.
You do get punished for earnings gained by those savings but that's to be expected because that is technically income.
