How much would it cost to buy a ticket to Mars?

I'm curious, could you elaborate on the potential cost of purchasing a ticket to Mars? Given the complexities and technological advancements required for such a journey, what factors would contribute to the overall price tag? Is it feasible for the average individual to save up for such an endeavor, or is it more of a luxury reserved for the ultra-wealthy? Additionally, are there any ongoing projects or initiatives that aim to make space travel more accessible and affordable for the masses?
