What exactly do you mean by “capitalist class”?
the class of people that makes a living through ownership of capital, they do not need to sell their labor, as opposed to workers which need to sell their labor to survive.
Is that only the people that dont work at all?
it is people who do not need to sell their labor to survive, they make their living through taking the surplus labor value that workers generate. (they may also choose to work, but this doesn’t change their position, they have a choice to work if they desire, unlike a worker which doesn’t have a choice)
And why cant those capitalists and the “working class” BOTH have power over the government?
because one class here has more leverage over the government, and so in a conflict of interest the government sides with the capitalist class as can be seen during any economic crisis (or crisis of any kind really) where austerity measures are immediately implemented and worker rights are rolled back.
how does each member of the “capitalist class” have any more influence on the government than each member of the “working class”?
they do on average, but you’ll easily be able to find a small capitalist that doesn’t have more power than you to control the government.
the thing is, here we are talking classes and class interests, if those who control the government belong to the capitalist class then the government will do things that benefit most members of the capitalist class, there doesn’t need to be direct control by every single capitalist for them to benefit from capitalist control over the government.
to give an example, regulatory protections to protect employees from hazardous working conditions may be removed through the direct influence of amazon or some other large corporation, but, smaller capitalist corporations also benefit from this as they stop having to take on the cost of providing a safer working environment (they can exploit their workers more fully), in this way, the government is controlled by capitalist, but not every capitalist controls the government, yet the government works for the benefit of the entire capitalist class.
if everybody votes, the government represent the interests of the whole population
This is simply false, representatives in the majority of neoliberal ‘democracies’ are not held accountable to the wishes of the people they are representing, and cannot be removed from their position with a simple majority from those who elected them, so then these people look towards those with influence (corporations, rich capitalists, etc) and then do things to please those groups in order to gain favor with them, like campaign donations, lavish luxurious trips and vacations, positive coverage in capitalist owned media, etc
(still disregarding lobbying)
Lobbying is not the only lever of power the capitalist class uses, the private ownership of mainstream media by capitalists means that all of their coverage would push capitalist interests, campaign ‘donations’ and funding is also used for control, to choose the candidates who represent your interest as a capitalist the best to win, and the candidates themselves are more likely to win if they come from a rich well connected upperclass background (meaning they are most likely capitalists themselves)
Regulatory capture is also a thing
There’s also the fact that capitalists also fund think tanks to publish studies that support their interests (no matter how far from the truth they have to stray) and are then used to support legislation that is in their favor (see global fossil capital and climate change), there’s also lots of astroturfing that goes on
And if lobbying were the issue, we could just ban it…
Even if you outlaw lobbying capitalists will still control the government in a myriad of other ways, capital flight being an example I didn’t mention in this reply yet,but this one is very strong and the US/WTO/IMF enforce it on as many countries as they can, the only way to have actual democracy is through forceful suppression of the capitalist class, only then you could imagine having a government actually controlled by the people while still having a capitalist market and a capitalist class
