Depends what you mean, if you mean "today" as to mean in the near future, then yes. But that does not preclude the possibility of class struggle opening up in the future. When women find themselves fighting against the government even with a female president, the minority of them who aren't deceived by the "it's because the congress doesn't let her 'x'" bullshit they will come to communism. Same things goes for white workers and if there is a Trump presidency (which I doubt though). This process will continue on, maintaining a revolutionary core in the proletariat, and eventually capitalism will be forced into world war level inter-imperialist warfare to restore the rate of profit, but before that point the state will become less stable as the bourgeoisie breaks even more into internal struggles over maintaining the economy with state-led/funded production, or it paying back its debts (which is impossible, as everything the state uses at the end of the day comes from the private sector or infringements on its market[s]). The signs of the outbreak of this crisis within the capitalist class are already showing for everyone to see (Brexit and Labor party crisis [Corbyn]. S█████ and the crisis over Trump [the capitalist class really pushing for Hillary]).
If you mean "today" as meaning "from now on", then this is simply untrue, as I explain above.
Things are never unchanging, We are in a certain part of capitalism's life, and it too will come to pass, even if that might not be in the next decade.
Not at the moment, no. But as I explain above, this is not a permanent phase of capitalism.
In capitalism yes, but the communist mode of production cannot develop within capitalism. Communism isn't "financed", it is the ending of the regulation of production by value. This is necessarily a global revolution, the proletariat is a global class and can only abolish itself with resources from all over the planet. The obtaining of resources for building communism happens by expropriation, by the proletariat unified in its dictatorship, guiding itself through its party (which is not the controller of the dictatorship, btw). One of the first steps taken by the proletariat in its dictatorship must be the abolition of money to be replaced by labor vouchers.
"Financing" implies capitalist social relations, and you can't transcend capitalism by using capitalism. No state authority or "horizontal" organization can overcome this, only the world proletariat can by changing these relations themselves (smashing capital and its state, collectivizing the home [destroying gender], completely destroying bourgeois society and rebuilding society anew, ending their existence as "workers").
But this isn't the human community, you are trying not to follow capitalism's rules while staying inside capitalist social relations, this is Utopian nonsense. You will find capitalism re-asserting itself at every step. You may deny it like stalinists will deny the capitaist inner-workings of the USSR, you may complain that they were not part of the plan, or that people aren't listening to your plan, but it will happen.
Your idea that capital and its state is permanently stable is extremely mistaken.
Might I suggest a (relatively) short critique of Marcuse's position (from the Frankfurt school) who though the same thing. BTW, Marcuse himself told Mattick (the author of the critique) that he thought his critique was the "the only central criticism".
PDF is of the critique, taken from marxists.org/archive/mattick-paul/1972/marcuse.htm
pic related is relevant info about Mattick when he was in America (he's from the German-Dutch tradition of the Communist Left), taken from a review of a book on Mattick:
