You appear to be ridiculously jealous OP. I thought the article would be about some kind of obscure tax avoidance scheme, but no, it's mainly bog standard advice that's found in places like Money Saving Expert, who addresses the mass market. Put the maximum into ISAs and increase your own and your spouse's pension contributions, hardly outrageous and perfectly sensible.
Whatever you're trying to claim, people who receive benefits, as a whole, are net takers. Ok some of them work, but most do not. If they do work, by the fact they're on benefits, means they have low salaries and therefore pay low tax.
I think it's much more disgraceful that the amount of benefit fraud is so high and, having read threads on here about that, it seems that huge numbers of people don't care at all about that and wouldn't report someone who told them to their face that they were fiddling the system. I think that we should go back to the days when I was younger( I'm early sixties) when to have to be on benefits was something shameful and only for emergencies, and hopefully temporary, rather than something that in some demographics is an alternative lifestyle choice to working.
So no, a bit of perfectly normal financial advice isn't wrongly lauding and applauding people who have got some money to invest. It's hardly telling people to set up complicated offshore trusts in the Cayman Islands.
