The government would like to outlaw pyramid selling. Why? Rachel Royce has joined Hearts, the girls-only investment scheme, and finds it good, clean – and profitable – fun I have a confession to make – but please don't tell my boyfriend. I've made a somewhat high-risk investment. It will cost me £375, but for that I can expect a return of £6,000 – maybe. It's a gamble – I know it's a gamble – but I thought that amount of money could be laundered from the housekeeping, lost somewhere among the cornflakes and the chardonnay and bailiff demands for forgotten Blockbuster videos.The scheme I've invested in is known as Hearts, and it's for women only. It calls itself a 'gifting scheme that benefits all women'. Men aren't allowed in because they'd ruin it with their incessant cynicism and greed.
