When was a lasagne considered unhealthy eating anyways? But you're right. Asda's prices like that are hard to beat. Unless you start cooking on a larger scale.
I think the 'unhealthy eating' remarks were more aimed towards those who get takeaways (Mcdonalds, kfc, BK, fish n chips, pizza, etc.)
There you go, a 1.5kg ready made lasagne or 3 cheeseburgers from Mcdonalds.
A cheeseburger has 303 calories which is only around 60% of the lasagne portion.
I agree that the poor living off takeaways could afford to eat a modestly healthy & balanced diet, but the poorest are not living off those - it's low quality cheap branded oven food (which really is much cheaper).
Also, to eat a well balanced mix of fresh vegetables & meats with any decent flavour is significantly more expensive than cheap crap but satiating own brand oven food.
Then you need to factor in eating pesticide ridden cheap tasteless vegetables compared to organic fresh ones. While frozen vegetables are an option, they do taste terrible comparatively & it's easier to see why some opt for the better tasting but unhealthy option when the healthy option within their price range. Then you have to factor in that in many cases peoples eating habits are heavily influenced during early childhood (which the child has no real control over).
To be fair, all this is immaterial to the key criticisms of these plans as we are not currently residing in a jobs surplus. Yes there are always 'some jobs around' but there are never 1.9 million jobs around, meaning a number just circle in & out of employment.
I'm fortunate, I had good parents who taught me a number of skills which have enabled me to do reasonably well in life in a specialist field, on-top of that I had a childhood free of abuse & suffer no alignments which would prevent me to succeed. I either lacked the genetic propensity or the misfortune to have the environmental triggers occur to gain the traits common to leading to long term unemployment.
How hard I work is irrelevant, as I didn't pick in advance the ability to work hard. This is why I object to strongly to ideological changes so based upon the 'self-made man' fallacy - ie, pretty much Conservationism in a nut shell - it's factually flawed & inconsistent with the world we actually reside within.
