I made me German 4 years ago, when I took on German citizenship. I didn't have to 'give up' my UK citizenship, but now my passport has run out and I didn't bother renewing it. The programme dealt too much with just stereotypes and 'averages' - but there is obviously much more to being German than just eating pork and drinking beer (two activities which no one in my family does!).
I moved to Germany from the UK 32 years ago. I do about 30 minutes of housework a day, share the cooking, and shopping with my husband and we have a Turkish cleaning lady who comes in for 3 hours once a week. I also have 3 children (now all 'grown up') and am a university professor, so I guess that is 'professional'. But we are not 'average' - and live in our own house, not a rented flat. The TV programme was very much directed at some kind of typical 'average' family. Rented flats do have 'rules' - mostly concerned with cleanliness (cleaning the stairs), and noise - but you can definitely use dishwashers, washing machines and even hoovers on Sundays - (but maybe not hang out washing in the 'public' areas). The lack of all-day schools, emphasis on mum's helping kids with their homework, not enough childcare facilities, and a tax structure which makes it seem like it is not 'worthwhile' for mothers to go back to work part-time is the reason why (in the past) many women stayed at home or only worked part-time with children. Career women often just don't have children - but also find it difficult getting to the top in a primarily male working environment. However, things have changed a lot during the past 30 years, and are still changing. Now more young dads are taking 3 months or more parental leave, and with guaranteed childcare provisions theoretically now becoming a legal right as of this month - more young mums will definitely be going back to work once their children are 1 or 2 years old. But not all children in Germany attend 'Forest Kindergartens' - although they do exist - and although the children start school late (6 or even 7) - they then have to work hard.
What's good about living in Germany? The political system - without the Green Party they would not have abandonned nuclear power stations, ecological awareness, community spirit, nice living environment (we live in a small town with next to an organic farm, but just 40 minutes direct train link to downtown Frankfurt) - the wine festivals, arts and culture, open-minded people, workplace co-determination, bike paths, good sports facilities.
