Marx’s theory of capital was focused on the ratio of profits, not on their mass. Attacking it by saying we have so much good under capitalism does not disprove the theory, because it is simply a statement about the mass of goods.
Marx said that under capitalism companies maximise profitrate. (Not profit!) Suppose there are two strategies:
Strategy A gives a worker 200 dollars, and they produce 500 worth of goods.
Strategy B gives a worker 500 dollars, and they produce 1000 worth of goods.
Strategy A will win, because it will give 1.5 dollars for each dollar of investment, while strategy B only nets 1 dollar for each dollar. The mass of profits is higher in the B case, but the focus is on return of investment.
Usually, automatization and technology improvements rises profitrate and revenue at the same time, and the life of the avarege worker improves.
Yet, independent of the total mass of revenue, the question about the ratio of distribution remains. If the ratio of wages increase, the ratio of profit would decrease, therefore the owners should want to lower the wage-ratio, while workers should want to increase it. And this is the key moment in the class struggle.

You seem to be conflating ‘amount of money paid to the worker as salary’ with ‘amount of capital used to equip the worker’.
