I think you need to look at the entire economic system.
If Tesla becomes wildly successful and thus displaces jobs in the ICE industries, gas and oil, repair and maintenance, healthcare, etc., yes, jobs will be lost. This will be the direct result of EV's and electricity offering a more efficient way to carry out the needed functions. So, the end-users, ultimately all of us, get more for less.
Tesla, the company, will receive some of the benefits directly in the form of profits. These profits will either flow to shareholders where they can be spent in the general economy or they will be re-invested by the company expanding, building new factories, and researching and developing new products, processes and technologies. The capital freed up by the efficiencies of electrifying transportation and energy markets will not be wasted. This is the capital that makes economies dynamic and useful and allows a wider diversity of jobs and economic opportunities.
In America, before food production was automated starting with the threshing machine in the 1780's, 90% of the working population worked in agriculture. This was hard, dirty, low-paying work that the threshing machine replaced. Jobs were lost and would continue to be lost as advances in food production increased efficiencies and the standard of living which, in turn, created demand for new jobs in new industries. People now had not only more money but more time to spend increasing their quality of life in other ways. The same kind of changes will happen as the electrification of energy and transportation markets increases economic efficiency. With cleaner air, our cities will have healthier populations needing less health care. This will save billions in federal healthcare costs and private employee sick leave. I could go on and on but suffice to say that increased efficiencies are always good for the economy and people's standard of living and Tesla is leading the charge.
Do not fear better ways of accomplishing the same thing.
