Not without grassroots movements and uprisings. Especially when it comes to stuff like labour laws and slavery. If factory owners got their way, we would still have worked 12 hour workdays 7 days a week. The wealth was not shared with the people, anything gained was taken by force in the form of unrest and movements. In many ways the French Revolution was the subtle threat to every nation unless they gave the people what they wanted.
Then not to mention stuff like women's rights and civil rights, which were not given thanks to wealth, but again due to grassroot movements and civil unrest. In many ways we still are facing tons of inequality today, due to the profit incentive of the people with wealth. See rising wealth inequality for example. If wealth and capitalism is what gave regular people political power, why do we not see this trend continue today?
If anything, I'd argue we got democracy and political power in spite of capitalism and concentration of wealth. Maybe it has more to do with the developed technology than with the economic system. Stuff like the printing press and easier access to knowledge. Requiring an educated populace to operate factories and producing more complex technological items. These kinds of stuff paving the way towards people getting "funny ideas" and thinking back on their position in the world, no longer accepting what was the status quo, but instead striving for something better.
I'd even argue that today's capitalism is a compromise, because the people in power tried their hardest to stay in power, but not the ideal that we could have had.
