No it’s a magical startup where it’s just going to be her in a basement doing 100% of the work required for 10 months straight while demand doubles every month.

Let's say she has ten employees. They all voluntarily agree to work for her: slavery is illegal, so people work for others on a consensual basis. Both the employer and employee negotiated and consented to a salary or wage schedule for that employee. The employer pays the agreed-upon compensation, and the employee receives it.

If the company makes an unexpectedly large profit, the employer is not obligated to redistribute that to her employees in addition to the already agreed-upon and paid compensation. If the employees think that what they agreed to work for is no longer sufficient, they are welcome to renegotiate their compensation or, if they feel they have been wronged and are being paid less than they are worth, to take their talent to a different employer. After all, everything so far has been consensual. The only thing that would be non-consensual would be obligating the employer to redistribute her profit over and above what had already been negotiated.

Let’s not be silly. If there are 10 people each with 10% and the company grows by 93%, then everybody’s shares, including the founder’s, grows by 93%.

Yeah math is wrong. She has to wait one more month to be a billionaire since she has a co-founder. So 10 months.

The good news is she can be a trillionaire in another 10 months.

Not giving everyone equal % is exploitation?

Interesting, by that logic every participant in the economy should also be required to bail out any startup that fails otherwise we’re exploiting the founders! They’re taking all the risk and we’re getting all the benefit of the services and goods they create!
