The foreign aid is mostly dealing with the fact that Israel is surrounded by hostile countries. Those countries are also hostile to the US, so it's really paying Israel to be its toe hold in the Middle East.

That is a deeply uncomfortable relationship for a whole lot of reasons.

But it's mainly aimed at the military. The country is otherwise pretty wealthy on its own terms. It's got a GDP per capita of $55k per person, mostly from manufacturing and tech, plus agriculture. So it generally has a European level of culture.

Regardless if there is voluntary long-term adoption of such technologies by a relatively free market vs. regulatory capture that leads politicians to arguably poorly-wastefully investing in technologies and companies pulling from the public coffers politicians have been entrusted with protecting; instead of the company and their technology, their offerings, gaining "votes" by consumers one-to-one buying the products, giving them profits and building more competent investors' confidence that the startup/technology is a actually good bet; of course the VC industrial complex has the whole hype up process for pump and dump, onto the public markets, so end consumers may become invested into bad investments if their stock broker and them aren't aligned properly incentives wise.

There's already a battle between mass produced and arguably unethical-inhumane living conditions/processes of the chicken industrial complex vs. small-organic farm raised chickens [of which overall arguably is losing and will remain suppressed even if it's what consumers prefer due to things like economies of scale and government subsidies that stack in favour to industrial complexes], and so adding a cultured "meat" into the food industrial complex landscape becomes more of a competitive battle between the existing handful of centralized incumbents and this new method of producing "food" [whether healthy or not] - which has the lowest manufacturing-distribution costs, and is policy structured to allow the general-mass population of people to have enough money to afford more than what is the cheapest.

There is also arguably a war within this industry, and perhaps foreign bad actors who may also be attempting to destroy our food production hoping for various outcomes, whether causing a reduction in supply and so an increase in price-profits, or other; I'll let your own creativity and imagination take you there, extrapolate further if you're connected to and spent much time already integrating the shadow.

P.S. The above of course isn't specific to Israel, many, if not most governments seem to do this to various degrees to "support" industrial complexes.
