Diversify in as many areas as you can. In income terms, diversify away from a single source by learning new skills, training up in areas you're a bit rusty in, learning totally new ones. In savings or investments: diversify where you put them, spread them around so you're not dependent on any one scenario. In eating: eat more interesting and cheaper things. Become vegetarian, if you aren't already. In exercise: drop…
> Become vegetarian, if you aren't already. A laudable goal in terms of sustainability and health, but in most developed countries not a cost saving measure. Meat is way too cheap, and often forms part of the bargains supermarkets use to attract customers. In the long term and the most pessimistic scenarios doing without meat may be cheaper though.
Where I live, this is no longer true; on the one side there was a big outrage at the super cheap meat (€3 / kilo at the lowest), pushing shops to sell meat at a higher price (and presumably better animal conditions, but I'm not convinced this is independently verified), on the other there's these certifications farmers can get for their animals' living conditions, and people are willing to pay extra for this.
Anyway, in our household, freezer vegetables are a staple. We tried fresh vegetables for a while, but there's a lot of stems (in e.g. broccoli) and it's not as fresh or affordable as the frozen stuff.
That said, I think that instead of raising the price of meat, they should lower the price, availability and diversity of vegetables.
I would also encourage people to avoid these "vegetarian meat alternatives"; they're kinda scammy in that the ingredients are cheap but they sell it at meat prices. It's a lazy vegetarian's option. If you want to avoid meat for whichever reason, learn to make meals without something that kinda looks like meat.
