I think the issue here is that people should have choice. Some people enjoy cooking and others don't. Both of those things are ok.
These days, those who don't enjoy it have other options that were not available in the past. Those options may or may not be to everyone's personal taste, but for a busy parent who works full-time, doesn't have a car and doesn't have the luxury of living next to a market with cheap fresh fruit and veg, they may be a godsend, and that's ok.
When it stops being ok is when people start to judge one another for their choices, or for what circumstances dictate that they do - sometimes choice doesn't come into it. I mentioned my friend upthread. She could make a cheap and nutritious meal easily, but getting her hands on the ingredients was a challenge. If you are feeding three under fives and 20% of your food bill would go on a weekly taxi to the supermarket, or on a bus every other day, so that you can carry the bags home, you are more likely to fall back on the local shop, even if it is more likely to sell frozen chicken pies than fresh chicken and vegetables.
As for people spending large sums on eating out - IMO that is entirely irrelevant. Unless we all lived on the same basic budget and any surplus had to go to a fund to feel the 'less fortunate' we all make choices about how to spend any extra money we have. It is no more or less ethical to spend on restaurants than on bibles or anything else. In a capitalist society, the vast majority of us has more than we strictly 'need', and it's hypocritical to pretend otherwise or judge others for spending on things that we might not buy - we will be buying things of which others could judge us, too.
In happier news, my friend's life improved over time, and she likes nothing more than eating in expensive restaurants when she can - she went to The Ivy for her 60th birthday celebration

My dad still cooks better than me and he's 71
