A few suggestions that would incentivise actual growth and improvement rather than market fraud and personal enrichment.
Cap CEO compensation to a reasonably "fair" multiple of their workforces average. Compensation type must match that average as well (cash/stock/scrip.) Bonuses follow the same rules.
Stock buybacks require the company to commit to both workforce and r&d budget increases of the same value before they can be done again.
Mass layoffs require issuance of new stock that match the % of the workforce cut.
