When my partner and I met she was a libertarian and I was a Obama loving lib. When we first started dating, we had both become "progressives" and canvassed for Bernie. Now we are both anarchists who would happily fight alongside MLs if the opportunity for revolution were ever upon us.
My message is this: together, you and your partner can extremify each other far beyond where you were likely to reach alone in the most virtuous of cycles.
If you started with $100M, you definitely could buy yourself a house and car before donating the rest. Hell, you could buy it out of the $2M and still be better off than most folks.
