is being a tech/dev person, a dead end job?

i have been thinking about this for sometime. as a dev, we can progress into senior dev, then tech lead, then staff engineer probably. but that is that. for a tech person :

1. their salary levels are defined. for eg, a junior may earn $10k pm , and the highest tech guy (say staff engineer) will earn $100k pm, but everyone's salary will be spread over this range only, in different slots.

2. some companies give stocks and bonuses , but most of the time that too is fixed to say 30% of the annual salary at max.

3. its a low risk job as a min of x number of tech folks are always required for their tech product to work properly. plus these folks are majorly with similar skills, so 2 react guys can be reduced to 1 but not because of incompetency .

4. even if people are incompetent, our domain is friendly and more like a community learning stuff. we share our knowledge in public domain and try to make things easy to learn for other folks inside and outside the office. this is probably a bad thing too

compare this to businesses , management and sales they have different:
1. thier career progression : saleman > sales team manager> branch manager > multiple branch manager(director) > multiple zones/state manager (president) > multiple countries/ company manager (cxo)

2. their salaries are comission based. they get a commission in the number of sales they get, later theybget comission in the sales of their team> their branch > their zone and finally in company's total revenue. this leads to very meagre number in salaries, but a very major and mostly consistent and handsome number in commission. that is why their salaries ranges from $2k pm to $2-$3millions per month.

3. in sales/management , their is a always a room for optimisation . if a guy is selling less products, than another guy, he could be fired and leads could be given to other/new person. managers can optimise the cost/expenses chain and help company generate wider profits. overall everyone is running for (a) to get an incentive and (b) to dodge their boss's axe.

4. this makes it a cut-throat and a network-first domain. people are arrogant and selfish, and have their own special tricks and tactics to ensure their value.

as a manager , you don't go around sharing the stories on how you got apple to partner with foxconn for every iphone manufacturing, you just enjoy the big fat bonus check and awe of inspiration that your junior interns make.

this sound a little bad , but on the contrary , this involves being a people person and a social animal. i remember one example from the office web series, where different sales people would have different strategies for getting a business: Michael would go wild, Stanley would connect with people of his race, and Phyllis would dress up like a client's wife.
in real life too, i have seen people using various social cues to get business. the guy from whom we bought our car, he was so friendly with my dad, i once thought that they are some long lost brothers.

this makes me wonder : are sales/mgmt people being better at being entrepreneur and human beings than we devs?

in terms of ethics, i don't think that people who are defining their life around comissions and cut throat races to be friendly or supportive beings. but at the same time, they would be connecting with people and their real problems, so they might become more helpful than their friends/relatives and other "good people" ?

Additionally, the skills of sales/mgmt translate directly to entrepreneurship, so every good salesman/manager is a billionaire in making. whereas we devs are just being peas in a pod , debating on next big npm package and trying to manage taxes on our already meagre , "consistent" income :/

mann i want some people skills like these guys
