I always assumed the amount of travelling that Tamara does is for tax reasons. There must be some kind of ‘tax management’ going on there.
She probably doesn’t think she is harming her daughter as she had a similar ‘jet set’ upbringing. The problem is is that Tamara does not realise how vapid she is. I remember before she settled down, she was on TV and it was completely empty other than shopping, and when she had Fifi, she said her life now had meaning. Except it doesn’t, because she still does all the pointless shopping and spending for her daughters.
