[Mario] What lead the goombas to collaborate with Bowser when he invaded the Mushroom Kingdom?

Were the goombas a low status caste within the Mushroom Kingdom, dissatisfied with the lowly position in society, and Bowser recruited them by promising a better lot in life?

Were the goombas forcibly conscripted into Bowser’s forces, but they’re sufficiently motivated soldiers (whether out of fear or duty) for Bowser’s cause that Mario has no alternative but stomping them?

Are they just mercenaries working for money?

When you're as physically weak as most Goombas, the smart thing to do is to side with the winner. Before Mario came into the picture, Bowser had the clear advantage. Now, sadly, most live in fear of the Koopa Troop and saunter forward only to avoid being hassled by them.
