Well... As unpopular as it is to some, many government or government contracting jobs are definitely jobs that matter.
It is interesting that you place a high value on Tesla when they are not even the affordable EV option. Is it the self driving aspect? Honestly curious what Tesla may be doing that other EV manufacturers really are not (other than being used as a status symbol).
Maybe I misinterpreted what "matters" means to you. I guess you mean a high valued position to a company? I originally interpreted it as a role with positive impact to society.
