Is it a likely progression? And how long do you believe it will take? Also, I’m curious what you are basing your hope on and what the you believe the knock-on effects will be. It would be good to know if something similar happened in the US or another country in order to compare.
I think it’s a reasonable assumption, but the reason I was asking for the basis for that hope is because I was hoping you had done some research and found some data to base that assumption on. It could have been a solid basis for it. In the UK, where Brexit was touted to achieve the same goal, the wages did go up (not a very good source, but well) however they ended up asking for the pickers, truck drivers, and handiworkers to return (EuroNews 2021, BBC 2023, Le Monde).
If you were to take a look at Germany (3rd biggest economy in the world), it struggles to get workers for elderly care and instead of increasing wages to attract more people, they are instead making easier to hire abroad e.g India.
I agree that the cost of food and landscaping will go up, which could be troubling for some who hoped for the opposite. Given how wages have not risen at the same rate as inflation, it is difficult to share your hope for increased wages - be it for the pickers and landscapers or the people paying for the produce and services. But, I may be wrong, I’m not a psychic either.
I do commend you for willing to pay more for ethically grown (and harvested) fruit. Whether your fellow countrymen and women are is yet to be seen.
In conclusion, my fear is that while there might be mass deportations and a real chance of wages going up, IMO the most likely outcomes are
Whether those are all good, whether they happen together or separately, I don’t know, but my hopes aren’t very high that the total outcome will be positive.
Good luck though.
