H1-B has other issues but regarding H1-B working for 10+ years, it is mostly due to country caps for green cards.
H1-B do get sponsored green cards, at least for the non-startup companies. IIRC, any H1-B having more than one extension i.e. > 6 years has to have a green card application pending. H1-B doesn't have country caps.
The green card system however has per country caps, which impacts primarily people born in India, China, Mexico,El Salvador, Guatemala, Honduras, Vietnam and Philippines. If you are born in Greece and come to USA on H1-B where a company sponsors green card for you, you would get it in around 1-3 years.
Source: Was born in India and also had a roommate from Greece who got green card in about 14 months after being in USA.
EDIT: Added El Salvador, Guatemala, Honduras and Vietnam to list of countries impacted based on https://travel.state.gov/content/travel/en/legal/visa-law0/v...
