> In cities, we will need chargers by every parking space
There are a number of alternatives that are not nearly as onerous. EVs do not need charging every day, and few people in cities need to drive every day. If you only drive 10 miles a week you can just charge once or twice a month; I already have to move my car twice a month for street cleaning.
IMO portable batteries are the most obvious solution. The lifetime-amortized cost of batteries is <20 cents per kWh, and for larger batteries with low discharge demands it's <5 cents. A small UPS-sized truck drives down your street in the afternoon, dropping off low-profile batteries underneath your car while another guy plugs them in. In the morning the batteries get picked up and taken to be recharged.
In the end the infrastructure is about the same level of effort, but I think the portable vision is much easier to conceptualize. A lot of jobs would be opened for people making these charging trucks. Many more would be opened to drive and operate them, but I'm not sure auto plant workers would want that.
> in towns/villages every house will need its own charger
Unfortunately these jobs are not transferable to auto workers. The processes to make chargers are highly automated, unlike auto manufacturing (outside frame and component production). There will be a lot of very well paying electrician jobs opening... but that's not a profession you can just jump into, despite the number of people who try (and cause fires doing so).
