Dumbing down or deskilling people serves the multinationals well: it's created a market worth about £4 Billion because the UK eats half of Europe's ready meals.
Its typical though to hear a Tory complain about something they have long encouraged.

The lack of a strong UK tradition of cooking is I suppose in origin the effect of both the Agricultural and the Industrial revolutions clearing people from a direct connection to the land, entailing the subsequent generational loss of their own distinct peasant skills.
